Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. Match each pair of points A and B to point C such

that ∠ABC = 90°. A(3, 3) and B(12, 6) C(6, 52) A(-10, 5) and B(12, 16) C(16, -6) A(-8, 3) and B(12, 8) C(18, 4) A(12, -14) and B(-16, 21) C(-11, 25) A(-12, -19) and B(20, 45) A(30, 20) and B(-20, -15)

The correct pairs in the boxes would be given as:

Tile 1 matches Tile 4.
Tile 3 matches Tile 6.
Tile 7 matches Tile 8.
Tile 9 matches Tile 2.
Tile 5 and 10 do not have pairs.

<h3>What are pairs?</h3>

These are values that are known to have x and y coordinates written as values and matched in brackets.

We have perpendicularity, when two lines intersect at 90° degrees angle,

For the first

A(3, 3) and B(12, 6)

The slope AB = ³/₉ = ¹/₃

Then BC would have a slope -1 ÷ ¹/₃ = -3

For C(16, -6); and slope B(12, 6)

we have = -12 ÷ 4 = -3

Tile 1 and 4 are a pair.

For A(-10, 5) and B(12, 16)

we have Vertical distance = 16 - 5 = 11

we have Horizontal distance = 12 - -10 = 22

we have Slope = ¹¹/₂₂ = ¹/₂

then The perpendicular slope would be -1 ÷ ¹/₂ this gives us -2

For C(18, 4) and B(12, 16)

we would calculate the Vertical distance to be 16 - 4 = 12

also the Horizontal distance would be 12 - 18 = -6

then its Slope BC would be solved as = ¹²/₋₆ = -2

Tile 3 and 6 would be a match

Next we have A(12, -14) and B(-16, 21)

First we solve the Vertical distance = 21 - -14 = 35

Then we go for the Horizontal distance = -16 - 12 = -28

The slope = ³⁵/-₂₈ = ⁵/₋₄

We solve the perpendicular slope as -1 ÷ -⁵/₄ = ⁴/₅

Try C(-11, 25)

Vertical distance with B = 25 - 21 = 4

Horizontal distance with B = -11 - -16 = 5

The slope = ⁴/₅

Tile 7 matches tile 8

Take A(-12, -19) and B(20, 45)

First we solve the Vertical distance = 45 - -19 = 64

then we solve the Vertical distance = 20 - -12 = 32

Slope AB = ⁶⁴/₃₂ = 2

perpendicular slope to be -1 ÷ 2 = -¹/₂

We have C(6, 52) and checking the slope with B(20, 45)

First we solve the Vertical distance = 45 - 52 = -7

then we solve the Vertical distance Horizontal distance = 20 - 6 = 14

The slope is ⁻⁷/₁₄ = -¹/₂

This would give us a pair with tile 9 and 2.
