Non-Isosceles Trapezoid
A non-isosceles trapezoid is a quadrilateral with one pair of parallel sides, called the bases, and the other two sides, called the legs. The bases are not congruent, and the legs are not congruent. The angles opposite the bases are called the base angles.
Properties of a Non-Isosceles Trapezoid
- The base angles are supplementary, meaning they add up to 180 degrees.
- The legs are not congruent.
- The diagonals are not congruent.
- The area of a non-isosceles trapezoid is given by the formula: Area = 1/2 – (b1 + b2) – h, where b1 and b2 are the lengths of the bases and h is the height.

Worksheet Answers: Non Isosceles Trapezoid And Isosceles Trapezoid Worksheet Answers
1. Find the area of a non-isosceles trapezoid with bases of 10 cm and 12 cm and a height of 8 cm.
Area = 1/2 – (10 cm + 12 cm) – 8 cm = 88 cm 2
2. Find the length of the diagonals of an isosceles trapezoid with bases of 10 cm and 12 cm and a height of 8 cm.
The diagonals are congruent and can be found using the Pythagorean theorem: d 2= (1/2 – (b1 + b2)) 2+ h 2
d 2= (1/2 – (10 cm + 12 cm)) 2+ 8 cm 2
d 2= 112 cm 2
d = √112 cm 2= 10.6 cm

FAQ Overview
What is the primary difference between a non-isosceles and an isosceles trapezoid?
Non-isosceles trapezoids have no congruent sides, while isosceles trapezoids have two congruent sides.
Can a square be considered a trapezoid?
No, a square cannot be considered a trapezoid because it does not have any parallel sides.
What are some real-world applications of trapezoids?
Trapezoids are commonly used in architecture, engineering, and design. For example, they can be found in the roofs of buildings, bridges, and even in the shape of sails on boats.
