Question

HELP!!! Find the lengths of the diagonals of this trapezoid.

Answer 1

Answer:

√[ (a + b)^2 + c^2 ].

Step-by-step explanation:

They are both equal in length because we have an isosceles trapezoid here. We see form the drawing it is symmetrical about the y axis.

The diagonal = the line joining points (b, c) and (-a, 0)

= √[ (b - -a)^2 + (c - 0)^2 ]

= √[ (a + b)^2 + c^2].
