Question

To determine if a quadrilateral is a isosceles trapezoid

Answer 1

To determine if a quadrilateral is an isosceles trapezoid, you need to check if the non-parallel sides are congruent.

Step-by-step explanation:

An isosceles trapezoid is a quadrilateral with two parallel sides of equal length. To determine if a quadrilateral is an isosceles trapezoid, you need to verify if the non-parallel sides are congruent. Here's how you can do it:

1. Check if the bases (the parallel sides) are equal in length. If they are not equal, the quadrilateral is not an isosceles trapezoid.
2. Next, measure the legs (the non-parallel sides) and compare their lengths. If the legs are congruent, then the quadrilateral is an isosceles trapezoid.
