Answer:
First of all, we can see that this shape have 4 90° angles.
Secondly, since x = 5 we have:
3 × 5 -2 = 15 - 2 = 13 (cm)
And: 5 + 8 = 13 (cm)
=> The two adjacent sides that make up the angle is equal to each other
So this shape is a quare.
=> This shape is a square.
1. The sides are equal.
2. All angles are 90° each.
It is a polygon that has four sides and four corners. The sum of the internal angle is 360 degrees. In square opposite sides are parallel and all the sides are equal and each angle is 90 degrees. And its diagonals are also equal and intersect at right- angles.
Given
The sides of the quadrilateral are (x + 8) and (3x - 2).
For x = 5, the first side will be
first side = x + 8
first side = 5 + 8
first side = 13
For x = 5,second side will be
second side = 3x - 2
second side = 3(5) - 2
second side = 15 - 2
second side = 13
1. The sides are equal.
2. All angles are 90° each.
