Are two scalene triangles with congruent bases always similar?
8 Always, Sometimes, Never. If two triangles are similar, then they are congruent. If two triangles are congruent, then they are similar.
Can two scalene triangles be congruent?
No, a scalene triangle cannot have two congruent angles. Congruent angles are angles that have equal measure.
Which pair of triangles is never similar?
Isosceles triangles are not always similar, but equilateral triangles are always similar.
Is a scalene triangle congruent?
A triangle without any congruent sides or angles is called a scalene triangle.
Are all right scalene triangles similar?
A right scalene triangle is a triangle in which all three sides are different in length and one angle is equal to 90 degrees. A triangle is a closed figure made up of three lines and three angles….Right Scalene Triangle.

Are all scalene triangles the same?
A Scalene triangle is a triangle that has 3 unequal sides. Since all the three sides are unequal, this means all the three angles are also of different measures….Scalene Triangle.

Are scalene triangles never similar?
A scalene triangle is a triangle that has 3 unequal sides, and an isosceles triangle has 2 equal sides. It is not possible for the two to be similar because for an isosceles triangle to have a similar triangle, that triangle must have two sides equal.
Is a scalene triangle and a right triangle always congruent?
A scalene triangle and a right triangle are never congruent. An equilateral triangle and a right triangle are always congruent.
Can scalene triangles be similar?
In order for two triangles to be similar, their angles must have exactly the same measures. In addition, the corresponding sides or the two triangles…
How many congruent sides does a scalene triangle have?
Difference Between Scalene, Isosceles and Equilateral Triangles
| Scalene Triangle | Isosceles Triangle | Equilateral Triangle |
|---|---|---|
| All three sides are unequal | Any two sides are equal | All three sides are equal |
| All three angles are different | Angles opposite to equal sides are equal | All three angles equal to 60 degrees |
Are scalene and equilateral triangles similar?
An equilateral triangle has all sides equal and each interior angle is equal to 60°. An isosceles triangle has two equal sides and the angles opposite the equal sides are equal. A scalene triangle has no sides equal. A right-angled triangle has a right angle (90°).
Does a scalene triangle have equal sides?
Scalene. A scalene triangle has three different angles and none of its sides are equal in length.
How are scalene triangles similar?
Scalene triangles have three sides of different lengths and three angles of different sizes. There are no lines of symmetry. An isosceles triangle has two equal sides and two equal angles and there is one line of symmetry.
How do you know if two scalene triangles are similar?
Two triangles are similar if they have:
- all their angles equal.
- corresponding sides are in the same ratio.
What is the properties of a scalene triangle?
Properties of the scalene triangle: All angles of a scalene triangle are unequal. A scalene triangle has no line of symmetry. The angle opposite to the longest side would be the greatest angle and vice versa. All sides of the given scalene triangle are unequal.
Are scalene and isosceles triangles always similar?
A scalene triangle and an isosceles triangle can never be similar.
Is a scalene triangle and an isosceles triangle similar?
Can a scalene triangle also be equilateral?
Note that all three sides in a scalene triangle are different. If two are of the same length and different from the third side, it’s neither equilateral nor scalene triangle.
Are isosceles and scalene triangles similar?
Can two triangles with the same sides be congruent?
Thus, two triangles with the same sides will be congruent. (Note: If two triangles have three equal angles, they need not be congruent. All that we know is these triangles are similar.) SAS: “Side, Angle, Side”.
How do you know if two triangles are congruent SSS?
SSS: Because we are working with triangles, if we are given the same three sides, then we know that they have the same three angles through the process of solving triangles. Thus, two triangles with the same sides will be congruent. (Note: If two triangles have three equal angles, they need not be congruent.
Are Sam’s triangle and Dan’s triangle congruent?
Dan also drew a triangle, whose angles have the same measures as the angles of Sam’s triangle, and two of whose sides are equal to two of the sides of Sam’s triangle. Dan claims that both triangles must be congruent.
What is the rule for similar triangles?
If two angles in one triangle are equal to the corresponding angles in another triangle, then both triangles would be similar to each other. This is called angle, angle or AA criterion. Rule 2 : SSS (Side, Side, Side) If all three corresponding sides of two triangles are in same proportion, then they are said to be similar triangles.
