Which are the coordinates of the vertices of a triangle congruent to ΔPQR?

(0,5), (2,10), (0,10)

(9,-3), (9,0), (4,0)

(4,3), (-4,8), (-4,3)

(2.5,-4), (0,0), (0,-4)

(4,3), (-4,8), (-4,3)

(2.5,-4), (0,0), (0,-4)

Step-by-step explanation:

On plotting on graph all form right angled triangle.

Dimension of all triangles and tanФ

Base=2 Height=5 tanФ 2.5 Base=5 Height=3 tanФ 1.6 Base=8 Height=5 tanФ 1.6 Base = 2.5 Height=4 tanФ 1.6

[Here base and height can be interchanged if needed]

Ratio of perpendicular and base of last two triangle is equal.

First two are not congruent to any of other triangle but 3rd and 4th triangle are congruent.

Their coordinates are:

(4,3), (-4,8), (-4,3)

(2.5,-4), (0,0), (0,-4)

Answer: C

(4,3), (-4,8), (-4,3)
