(-3,4)

200

What vector describes the translation below?

(Hint: the vector is written in the form (x,y) and describes the distance and direction of the translation)

(The light shape is the object, the dark shape is the image).

(0,-10)

300

Which of the shapes to the right is the reflection of the shape on the left?

Shape C

400

Which of the dark blue shapes is a rotation of the light blue shape?

Shape C

500

What is the point about which a shape is rotated called?

Centre of Rotation

Congruency

100

Which congruency test shows that 

/_\DEF-=/_\NML?

SSS - Side Side Side

200

Identify two pairs of congruent shapes from the options below.

A and C

D and H

300

Determine which triangle(s) out of B, C, and D is/are congruent to A. State which test(s) for congruence you used.

Shape D is congruent to A by ASA - Angle Side Angle.

note: 

Shape B: has two angles in common with A, but the side is a different length.

Shape C: this has two angles and a side-length in common with A, but to pass the ASA test the side-length needs to be between the two angles, which in C’s case it isn’t.

This pair of triangles are congruent. Find the value of the missing pronumerals a and b.

a = 50^o 

b = 90^o
