What is the rule for the reflection? a. ry=x(x, y) → (–y, –x) b. ry=–x(x, y) → (–y, –x) c. ry=x(x, y) → (y, x) d. ry=–x(x, y) → (y, x)

What could explain what happened when the time was equal to 120 minutes

True or false? a circle could be circumscribed about the quadrilateral below.

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
