“plot triangle abc with vertices a(0,0), b(3,4), and c(3,0) on graph paper. using the origin as the point of dilation, enlarge it by 2 factors (imagine using two rubber bands). label this new triangle a’b’c’.
a) what are the side lengths of the original triangle, abc?
b) what are the side lengths of the enlarged, a’b’c?
c) calculate the area and the perimeter of a’b’c.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

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.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
