What about them? It depends on the shape! All 2 dimentional shapes are made of triangles. A triangle has a total of 180 degrees inside. A square is simply 2 triangle side by side therefore totaling 360 degrees inside. (180+180). Penticon 3 triangles hence 540 degrees. This will continue for every side added to a shape then add 180 degrees. This will look good on your maths exam (Formilure (No of sides -2)x180=total degrees)

Why do some shapes make tilings and some do not?
It all matters what the inside angles measure up to. If the inside angles measure up to 360 degrees, the shape will tile. If the inside angles do not add up to 360 degrees, the shape won't tile.
How do you determine inside angles for trig?
The answer depends on the shape and what information you do have about it.
What is the definition of exterior angles and interior angles?
In a geometric shape (say a triangle), the interior angles are those measured on the inside of the shape. The exterior angle is the angle if you were to extend one of those lines to the outside of the shape and measure from that line segment to the other intersecting line. Interior + Exterior = 180 degrees
Can a congruent shape have the same number of angles?
a congruent shape HAS TO HAVE ALL CONGRUENT ANGLES OR IT WOULDNT BE A CONGRUENT sHAPE
What are extirior angles?
Angles on the outside of the shape
Do measures of the inside angles of the shape matter?
no
Is the size of the angles inside a pentagon the same as the angles inside a decagon?
NO because if you look at the shape it is different.

The answer depends on the shape and what information you do have about it.
What are the interior angles of a polygon?
They are angles between adjacent sides of the polygon, measured on the inside of the shape.
Can you have diagonals in irregular shape that includes reflex angles?
Yes. They may not be wholly inside the shape but that is not a necessary requirement.
What shapes contain only acute angles?
A triangle is the only shape that can have only acute angles inside it.
What are reflex interior angles?
reflex interior angles are the angle bigger than 180'c found inside a shape.
What is the total degrees of a shape that has four sides?
The four inside angles add up to 360 degrees.
What is the definition of exterior angles and interior angles?
In a geometric shape (say a triangle), the interior angles are those measured on the inside of the shape. The exterior angle is the angle if you were to extend one of those lines to the outside of the shape and measure from that line segment to the other intersecting line. Interior + Exterior = 180 degrees
What is a internal angles?
It is an angle that is bigger than 180 degrees and smaller than 360 degrees inside of a shape
What shape has two acute angles and no line s of symmetry what is the shape called?
If the shape has 3 angles in all, where two of the angles are acute, then the shape is a scalene triangle.
