If the areas of the 4 squares are 50, 32, 18 and 12, what is the ratio of the small shaded portion to the area of the large shaded portion? a. 1: 8
b. 1: 6
c. 1: 4
d. 1: 3
e. 1: 1

D. 1:3

Step-by-step explanation:

Given that the areas of the 4 squares are 50, 32, 18 and 12,

Area of the small shade portion portion = 18 - 12 = 6

Area of the large shade portion portion = 50 - 32 = 18

Therefore, the ratio of the small shaded portion to the area of the large shaded portion

= 6:18

= 1:3

Option D.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
