Four rectangles have the following dimensions:

rectangle a: 2 x 3

rectangle b: 8 x 12

rectangle c: 5 x 7

rectangle d: 10 x 12

which pair of rectangles is similar?

a. rectangle a ∼ rectangle b
b. rectangle b ∼ rectangle c
c. rectangle a ∼ rectangle d
d. rectangle c ∼ rectangle d
e. rectangle b ∼ rectangle d

sorry, i don't know i just need points, i'm new here. chao

can you make your screen more see able?

then i might be able to .

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
