On the graph, 2 right angles have the line as the hypotenuse. In this task, you will use these triangles to show that the slope between points E and A is the same slope between A and C Q1: which angles of the triangle measures 90°?

Q2: to show that the other 2 angles measurements in he's triangle are equal, you can use parallel lines cut by a transversal. Which 2 pairs of lines segments formed by triangle slides are parallel and what is the transversal for each pair?

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
