In the Cartesian plane shown: AB || ED and line segments AD and BE bisect each other at point C. Line segment CH is perpendicular to AB of triangle ABC. Find the equation of line segment CH. E(24, 34)
A(0, 42)
D(40, 2)

When you arrive at the lake, your friend realises he hasn’t got any swimming trunks. you need to ride to a sports shop. the sports shop is 8350 metres away. how many metres is it to cycle there and back?

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

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
