What is the difference between right angle triangle and all other types triangles?
right angle triangles have a 90˙ angle as one of their angles. All triangles' angles have to add up to 180˙, so the total of the remaining 2 angles has to be 90˙. Other regular triangles are non-specific, their angles just have to add up to 180˙ total.
What total angle measures always equal 360 degrees?
Circles measure 360 degreesAny quadrilateral as well.Try to picture this, if you take a rectangle, and make a diagonal line across it, you have two triangles. Triangles will ALWAYS measure up to 180 degrees, so since you have two, 180X2=360
What is the measure of each inntrior angle of a 5 sided polygon?
IT IS 900 THE METHOD IS IT HAS 7 SIDES AND 2 TRIANGLES SO WE SUBTRACT 7-2=5 THEN THE SUM OF INTERIOR ANGLE OF TRIANGLE IS 180 SO 5 INTO 180 WILL GIVE YOU THE TOTAL NUMBER OF ANGLES
What degree of angle for octagon?
For a Regular Shape (all angles measure the same), you can split it up into triangles to find the total angle measures. For example, in a square, you can only split it in half, making 2 triangles (below). A triangle always measures 180 degrees, so for an octagon you would split it into triangles from one point. If you count the triangles, you will have 8 triangles. Now Multiple 8 by i80, and your sum of angles will be 1080°.If you then divide it by the sum of the angles in a triangle, or 180 degrees, you will find that 1 angle measures 135 degrees. This rule applies to all Regular Polygons. If you still don't get it,try the link below
What is the internal angle of a hexagon?
120 degrees The way to figure any polygon is to draw diagonals from one of the vertexes to all the others and count the triangles. A 6 sided figure has 4 triangles. 4 times 180 = 720 total degrees. Divide that by 6 and you have 120.

What angle in a right triangle is the biggest and why?
The right angle is the largest. Triangles have a total of 180 degrees. If you use 90 on one angle, you only have 90 for the other two.
What is the total measure of the interior angle of a pentagon?
108o

If the measure of an angle is three times the measure of its supplement then find the measure of the angle?
x is the angle you're looking for and 3x is the angle that when added to x must total 180 degrees. Therefore the angle is 45degrees (x + 3x = 180)
If two angles of a triangle each measure what is the measure of the third angle?
180- total of the first two angles= 3rd angle

What is the angle measure of a 10 sided polygon?
Total 1440o; if regular, each angle = 144o
What is the sum of the angle measurement of a decagon?
Pick a point around the center of the polygon. Join each vertex to this point. You will now have 10 triangles. The total angle of these 10 triangles is 10x180 degrees. Now you need to subtract the angles of the ten triangles at the center (which is 360 degrees). Therefore total internal angles is (10x180)-360 = 1800-360 which is 1440 degrees.
What is the sum of the measure of an interior angle of an hexagon?
Each interior angle is 120o making the total 720o.
