Rotating a triangle by 90 degrees will change the measures of the interior angles by?
0
Reflection of a triangle will change the measures of the interior angles by?
0 degrees
What happens to area and perimeter of a triangle when it is moved?
Just moving a triangle, or rotating, or even reflecting (without scaling) a shape will not change its area or its perimeter.
Does the length of a side of regular polygon affect the sum interior angle measures?
No. Imagine any regular polygon ; a triangle, a rectangle a dodecagon or whatever. If they are regular polygons then whatever shape you choose they are just scaled up or scaled down versions of one another. Whilst the length of the sides can differ the sum of the interior angles does not change. The formula for calculating the sum of the interior angles of a polygon is 2n - 4 right angles, where n is the number of sides. This is not affected by the length of the sides.
Does measure of interior angles preserved under translation?
Yes. Under translation the shape does not change, only the position of the shape changes - the translated shape is congruent to the original shape.

As the number of sides increases how do the angles change?
When the sides of a regular polygon increases its interior angles also increases
How do the angles change when more sides are added?
They can change in almost any way that you like. The only limitation is that, if there are n angles, then their sum is (n - 2)*180 degrees.
What happens if the number of sides of an equiangular polygon is doubled?
The interior and exterior angles would change.
What happens to area and perimeter of a triangle when it is moved?
Just moving a triangle, or rotating, or even reflecting (without scaling) a shape will not change its area or its perimeter.
What does the cv joint on a car do?
It transfers rotating power from the transaxle to the wheels while allowing the suspension and steering to change angles.

What are the internal angles to 3 significant figures of a triangle when its perimeter is 150cm and its sides are in the ratio of 4 5 6?
82.8, 41.4 and 55.8 degrees The sides are 40cm, 50cm and 60cm so use the Cosine Rule to find the interior angles: Cos A = (b2+c2-a2)/(2bc) Change the formula to find the other angles
Why does the moon change Why does the moon change positions?
Because the Earth is rotating :D
Do the interior angle of a pentagon have to be the same measurement of the perimeter?
The angles of a polygon are not directly related to the measurement of the perimeter. If you measure a perimeter of a pentagon in inches and then again in centimetres, the measurement number will change but the pentagon will remain the same.
