Question

There are three types of triangles, and the area formula works for all of them. You can determine which type of triangle you're looking at by measuring the sides or angles. In an equilateral triangle, all three sides and all three angles are equal. An isosceles triangle has just two equal sides and two equal angles. And in a scalene triangle, all sides and angles are different.

Which of the following is an isosceles triangle?

A
a triangle with three equal sides

B
a triangle with no sides of the same length

C
a triangle with three equal angles

D
a triangle with two equal sides

Answer 1

Its D

Explanation:

Answer 2

D) A triangle with two equal sides

Explanation:

In Greek, "isos-" means "equal", and "skeles" means "leg". So, there will be two congruent/equal sides of the same length, along with two equal angles.
