The sum of the exterior angles of the triangle is 360
The sum of the exterior angles of the quadrilateral is also 360
The sum of the exterior angles of the pentagon is again 360
Each of the shapes has an exterior angle sum of 360
Answer:
Number 4 is neither, number 6 is perpendicular
Step-by-step explanation:
The reflection shown in the picture is an example of what's called a <em>rigid transformation</em>, one that doesn't deform the original shape in any way. Rigid transformations preserve lengths and angles, which means that the measure of some angle ∠A is going to be equivalent to the measure of the corresponding transformed angle ∠A'
Here, we see that the only response which represents that correspondence is the last one: m∠BCA = m∠B'C'A'
Divide
a = b * h
we know the base and area, not height
h = a/b
h = 70.8/9.44
h = 7.5
Your height is 7.5 units
First you want to find the length and width of the rectangle using the distance formula:
d=√(x2-x1)²+(y2-y1)²
AB=√(6-3)²+ (-2 - -2)²
AB=√3² + 0
AB=√9
AB=3
BC=<span>√(6-6)²+ (5 - -2)²
BC=</span>√0 + 7²
BC=√49
BC=7
We can find the area by multiplying these two distances together:
A=(3)(7)
A=21 units²
