Question

drag and drop the correct choice into the drop areas on the image above
base base angle leg vertex angle

Explanation:

In an isosceles triangle, the two equal - length sides are called legs. The non - equal side (if any) is the base. The angles opposite the legs are base angles and the angle opposite the base is the vertex angle.

1. The side opposite the vertex angle is the base. So the base should be dropped at the side opposite the vertex angle.
2. The angles at the base are base angles. So base angles should be dropped at the angles at the base of the triangle.
3. The two equal sides are legs. So legs should be dropped at the two equal - length sides.
4. The angle between the two legs is the vertex angle. So the vertex angle should be dropped at the angle between the two legs.

Answer:

Assuming the triangle is isosceles:

• 4: base
• 3 and 5: base angle
• 2 and 6: leg
• 1: vertex angle
