Answer:

J'(7,-4), K'(-7,-1), L'(-2,2)

Step-by-step explanation:

reflection over x-axis: (x,y) --> (x,-y)

reflection over y-axis: (x,y) --> (-x,-y)

Because the triangle is reflected x-axis and then y-axis,

all points would be (x,y) --> (-x,-y)

Given the regular polygon, what is the measure of each numbered angle?

ANEK [815]

Answer:

Answer A

Step-by-step explanation:

Approach 1

B, C, and D are wrong because angles 1 and 2 are congruent.

Therefore your answer of both being 60°

Approach 2

Let x = angle 1.

360/x = 6

x = 60°.

Therefore Angle 1 is 60°

An interior angle of a hexagon is 120°

Let y = angle 2.

y is half of 120°

So 120/y = 2

y = 60°
