The coordinates of the vertices of triangle abc are given in the table.
a = (4,2)
b = (6,7)
c = (13,1)
triangle abc is reflected across y=−x .

what are the vertices of triangle a'b'c'?

enter your answers in the boxes.

Solve the system of equations. y= 2x y= x^2 - 15

Which of these triangle pairs can be mapped to each other using two reflections?

In the following diagram it is given that dec, ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
