Answer:

bro all equilateral triangle are equal

Step-by-step explanation:

In geometry, an equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle, where each angle measure 60 degrees.

Answer:

1. True

2. False

3. False

4. True

Sep-by-step explanation:

Similarity:

 Two polygons of the same number of sides are similar if

  (i) their corresponding angles are equal and

(ii) their corresponding sides are in the same ratio.

  AAA similarity ,  SAS similarity , SSS similarity

1. True.

  Two polygons of the same number of sides are similar if their corresponding angles are equal. AAA similarity.

In an equilateral triangle each angle is 60°. So, all equilateral triangles are similar.

2. False.

 In each isosceles triangle, the  measurement of angles differs and so the shape wont be same.

3. False.

  In each right angle triangles, the other two angles differs and so, all right triangles will not have the same shape.

4. True.

   All circles have same shape and the only the size of the circle vary. So, all circles are similar.
