What are the coordinates of the vertices of the image of rectangle wxyz after the transformation r0, 90°(x, y)? w'(–4, –1) x' y' z'(–4, 2)

x'(-2, -1)

y'(-2, 2)

step-by-step explanation:

on the graph if you draw out the lines and show the rotation of 90° you will get those answers.

the first drop-down box will be x'(-2, -1)

the second drop-down bow will be y'(-2, 2)

step-by-step explanation:

when you rotate the rectangle around the point that it tells you to rotate, you will end up with the coordinates i have given. i hope i have !

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
