What is an isosceles trapezoid

The video tutorial explains the concept of an isosceles trapezoid, highlighting that it has equal opposite angles and sides. The teacher provides examples to illustrate these properties, asking students to identify equal sides and angles in given trapezoids. Theorems are not covered due to time constraints, but key points about isosceles trapezoids are emphasized.

What defines an isosceles trapezoid?

• All sides are equal

• Opposite angles and sides are equal

• All angles are right angles

• Only one pair of sides is parallel

If one side of an isosceles trapezoid is 13 meters, what is the length of the opposite side?

• 6.5 meters

• 13 meters

• 26 meters

• Cannot be determined

In an isosceles trapezoid, if two angles are equal, what can be said about the opposite sides?

• They are perpendicular

• They are equal

• They are parallel

• They are different

If an isosceles trapezoid has angles of 50 degrees, what is the measure of the opposite angle?

• 45 degrees

• 50 degrees

• 60 degrees

• 90 degrees

In the given example, if one angle is 45 degrees, what is the measure of the opposite angle?

• 50 degrees

• 45 degrees

• 90 degrees

• 60 degrees
