angle b = 90 degrees, side bc = 20, angle y = 90 degrees, and side yz = 20. what additional information would you need to prove that δabc ≅ δxyz by hl? angle a is congruent to angle x. angle b is congruent to angle y.
(c is wrong)

The additional information would you need to prove that ΔABC ≅ ΔXYZ by HL is

Side AC is congruent to side XZ

Step-by-step explanation:

Given:

Angle B = 90 degrees,

side BC = 20,

angle Y = 90 degrees, and

side YZ = 20

To Prove:

ΔABC ≅ ΔXYZ by HL

Proof:

In  Δ ABC and Δ XYZ

BC ≅ YZ     ……….{measure of each sides 20 given}

∠B ≅ ∠Y     …………..{measure of each angle is 90° given}

AC ≅ XZ     ……….{additional information}

Δ ABC ≅ Δ PQR ….{By Hypotenuse Leg Theorem}

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
