QUESTION 1

In figure A, the area of the bigger square is $625\:units^2$ . This means that the length of this square is the hypotenuse of the right angle triangle formed, which is $25\:units$ .

The area of the two smaller squares are $576\:units^2$ and $49\:units^2$ .

The length of these two squares form the two shorter legs of the right angle triangle, which are $24$ and $7$ units respectively.

Therefore we can write the equation, $576+49=625$ .

This implies that, $24^2+7^2=25^2$

We can see that the sum of the squares of the two shorter legs equals the square of the longer side which is the hypotenuse and this what the Pythagoras theorem says.

But in fig. B,

$5^2+4^2\ne 6^2$

Therefore the correct answer is Fig A.

QUESTION 2

See diagram.

We introduce the two lines as shown in the diagram.

From Pythagoras' Theorem,

$|AB|^2=|AC|^2+|BC|^2$

But $|AC|=|7-3|=4$ units.

and

$|BC|=|8-2|=6$ units.

This implies that,

$|AB|^2=4^2+6^2$

$|AB|^2=16+36$

$|AB|^2=52$

$|AB|=\sqrt{52}$

$|AB|=2\sqrt{13}$

$|AB|=7.2$ to the nearest tenth.

QUESTION 3

The numbers $3,4$ and $5$ form a Pythagorean triplet because $3^2+4^2=5^2$ .

If these numbers represent the side lengths of a triangular fence, then the triangular fence must be a right angle triangle.

The correct answer is B

Yes,because $3^2+4^2=5^2$ .

QUESTION 4

See graph.

We want to find the image of the triangle with vertices A(-5,-4), B(-2,-4), and C(-5,-1) after a reflection in the x-axis.

The mapping for this transformation is

$P(x,y)\rightarrow P'(x,-y)$ .

We just have to negate the y-coordinates.

$A(-4,-5)\rightarrow A'(-4,5)$ .

$B(-4,-1)\rightarrow B'(-4,1)$ .

$C(-5,-1)\rightarrow C'(-5,1)$ .

Find the perimeter of the following shape, rounded to the nearest tenth:

Mademuasel [1]

Answer:

B, 19.1

Step-by-step explanation:

Imagine that each side is the hypotenuse of a triangle. You want to use the Pythagorean theorem on each of these triangles to find the length of the side.

Let's start with AB:

One side of the triangle is the distance between the points in the x direction only. A is at the x-coordinate of -3 while B is at the x-coordinate of 2. The side is, thus, 5 units.

The other side of the triangle is the distance between the points in the y direction only. A is at the y-coordinate of 5, while B is at 6. The distance is 1 unit.

So we have a triangle with the base of 5 and the height of 1. The Pythagorean theorem says:

Base² + Height² = Hypotenuse²

a² + b² = c²

where a, b are the sides, and c is the hypotenuse.

Put our values into this, the base is 5 and the height is 1:

5² + 1² = c²

25 + 1 = 26 = c²

c = √26 ≈ 5.1

Repeat this for the lengths BC, CD, and DA.

x-difference = 2

y-difference = 4

4² + 2² = c²

20 = c²

c = √20 ≈ 4.47

x-difference = 5

y-difference = 1

(since this is the same as AB we can use that value ≈ 5.1 )

x-difference = 2

y-difference = 4

(since this is the same as BC, we can use that value ≈ 4.47)

Add all these together:

5.1 + 5.1 + 4.47 + 4.47 ≈ 19.14

(Note: this is not exact, but it's good enough for this purpose)

The closest option to this is B, 19.1 - thus, B is the answer.
