Question

1. label the isosceles below: a. b. c. d.

Explanation:

• Vertex angle (a): In an isosceles triangle, the angle opposite the base (the non - equal side) is called the vertex angle.
• Legs (b): The two equal sides of an isosceles triangle are called legs.
• Base angles (c): The angles adjacent to the base (the non - equal side) are called base angles. In an isosceles triangle, the base angles are equal.
• Base (d): The non - equal side of an isosceles triangle is called the base.

Answer:

a. Vertex angle
b. Legs
c. Base angles
d. Base
