Question

1. which triangle has two equal sides and two equal angles?

a. isosceles
b. right
c. equilateral
d. scalene

Explanation:

An isosceles triangle has two equal sides (called legs) and the angles opposite those equal sides (base angles) are also equal. A right triangle has one \(90^{\circ}\) angle. An equilateral triangle has all three sides and all three angles equal. A scalene triangle has no equal sides and no equal angles. So, the triangle with two equal sides and two equal angles is the isosceles triangle.

Answer:

a. Isosceles
