Exploring Isosceles Trapezoids
Isosceles Trapezoid
An isosceles trapezoid is a trapezoid with congruent legs.
Make a conjecture about each pair of base angles of an isosceles trapezoid.
Click Show sides and angles. What do you notice about each pair of base angles of the isosceles trapezoid? Move one of the blue points to verify your conjecture.
Make a conjecture about the lengths of the diagonals of an isosceles trapezoid.
Click Show Diagonals. What do you notice about the length of each diagonal of the trapezoid? Move one of the blue points to verify your conjecture.
