Question

an isosceles triangle has
select one:
a. 3 equal sides
b. no equal sides
c. 2 equal sides

a line has
select one:
a. 1 endpoint
b. no endpoints
c. 2 endpoints

Explanation:

1. For the first question: By definition, an isosceles triangle is a triangle that has exactly two sides of equal length. A triangle with 3 equal sides is equilateral, and one with no equal sides is scalene.
2. For the second question: In geometry, a line is defined as a straight one-dimensional figure that extends infinitely in both directions, meaning it has no endpoints. A figure with 1 endpoint is a ray, and one with 2 endpoints is a line segment.

Answer:

1. c. 2 equal sides
2. b. no endpoints
