What is equilateral triangle example?
An equilateral triangle is also called a regular polygon or regular triangle since all its sides are equal. Suppose, ABC is an equilateral triangle, then, as per the definition; AB = BC = AC, where AB, BC and AC are the sides of the equilateral triangle.
What are 3 equilateral triangles?
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°….

What is equilateral triangle with diagram?
An equilateral triangle is a triangle with all three sides of equal length , corresponding to what could also be known as a “regular” triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal.
What shape is a equilateral?
A shape is equilateral if all the sides are the same length. In geometry class, people learn about many shapes, such as triangles and squares. A square is equilateral, because all of its sides are the same length.
How many sides are there in equilateral triangle?
3Equilateral triangle / Number of edges
How many sides does equilateral triangle have?
How do you know if a triangle is equilateral?
If all three of the sides of a triangle are equal, it is equilateral.
What is equilateral triangle Class 7?
An equilateral triangle is the one in which all the three sides are equal. It is a special case of the isosceles triangle where the third side is also equal. In the triangle ABC, AB = BC = CA. Properties of an equilateral triangle are: It has 3 equal sides.
How many sides does a equilateral triangle have?
How do you identify an equilateral?
Equilateral Triangle: A triangle is said to be equilateral triangle if all the sides are equal. If X, Y, Z are three sides of the triangle. Then, the triangle is equilateral only if X = Y = Z. Isosceles Triangle: A triangle is said to be an isosceles triangle if any of its two sides are equal.
What are the angles of equilateral triangle?
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.
How do you make a triangle out of cardboard?
One cardboard box can make a large number of these, enough to build up a decent structure.
- Step 1: Mark and Cut the Corner.
- Step 2: Trace and Cut Out the Third Side.
- Step 3: Join and Tape.
- Step 4: Cut Out Holes for Connector Ties.
- Step 5: Decorate, Connect to Other Parts, Document and Spread.
What are the identifying features of an equilateral triangle?
The altitude,median,angle bisector,and perpendicular bisector for each side are all the same single line.
How does an equilateral triangle look like?
What does an equilateral triangle look like? An equilateral triangle is a 3-sided polygon (enclosed shape) that whose sides are all congruent (equal in length). An equilateral triangle also has 3 congruent angles, all 60˚ in measure.
Does an equilateral triangle have one right angle?
No, an equilateral triangle is equiangular. Equiangular means all the angles measure the same, so 180/3=60 degrees. By definition, a right triangle is a triangle with one right angle, and a right angle measures 90 degrees. No right angles are possible in an equilateral triangle, so no, an equilateral triangle cannot be a right triangle.
What type of angle does an equilateral triangle have?
The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. Click to see full answer.
