The triangle in this question is not drawn accurately. Use Pythagoras' Theorem to explain why triangle A must be right-angled.

Wewaii [24]

Answer:

We know the triangle in a right triangle because of the pythagoras theorem: 5^2+12^2=13^2

25 + 144 equals 169, making it a right triangle since the equation works.

What is the area of triangle ABC?

miskamm [114]

Answer:

<h2>7 square units</h2>

Step-by-step explanation:

As you can observe in the image attached, we know the coordinates of each vertex of the triangle.

To find the area using only its vertex coordinates, we need to use the following formula

$A=\frac{1}{2}[x_{1}(y_{2} -y_{3}+x_{2}(y_{3} -y_{1} )+x_{3}(y_{1}-y_{2} ) )$

Where the coordinates are

$A(1,1)\\B(4,0)\\C(3,5)$

Replacing coordinates, we have

$A=\frac{1}{2}[1(0 -5)+4(5 -1 )+3(1-0 ) ]\\A=\frac{1}{2} [-5+16+3]=\frac{1}{2}(14)\\ A=7$

Therefore, the area of the triangle is 7 square units. So, the right answer is the second choice.
