Square ABCD lies on a flat surface and has regular hexagons attached as flaps on sides AB and AD. Each flap is folded t degrees upward until the sides AE and AF coincide.
What is the value of t? What is the minimum angle made by AE with the surface of the table?
Suppose ABCD is an isosceles trapezoid with bases AB and CD and sides AD and BC such that |CD| > |AB|. Also suppose that |CD| = |AC| and that the altitude of the trapezoid is equal to |AB|
If |AB|/|CD| = a/b where a and b are positive coprime integers, then find a^b?
Quadrilateral ABCD has AD = BC, ∠A + ∠B = 90°, AB = 20, CD = 10, as shown below.
What is the area of ABCD?
Rectangle ABCD is made up of 5 equal rectangles, as shown. Point E is on side CD, and AD = 10. What is the area of triangle ABE?
A triangle with sides AB = 3, BC = 4, and AC = 5 has an inscribed square PQRS with side QR along the side AC. What is the area of the square?
