PQR and XYZ are similar right angled triangles. A) work out the length of XY
Note:your finial line should say "XY=."
(2 marks)
Rectangles ABCD and DEFG are congruent.
AB= 7cm
AD=3AB
B) work out the length of CE.
Note your final line should say "CE=..."
(2 marks).

XY=4

CE=14

Step-by-step explanation:

A)since the 2 traingles are similar, there is a ratio between the 2 of them. we can find that by dividing the side :10/25 =0.4. so XYZ is 0.4 of PQR. to check that we can try to multiply pr by 0.4 to see if it gets XZ. 25 • 0.4 =10.To get XY we will do the same thing: PQ • 0.4 = 10 • 0.4 = 4

B)AB= 7

CD= AB =7

AD = 3 AB

AD = 3•7

AD= 21

Since ABCD is congruent to DEFG

AD =ED = 21

CE = ED-CD = 21-7=14
