The sum of the angles of a triangle equal 180 degrees. The sum of the angles of a quadrilateral equal 360 degrees.
To find the measure of an angle for a triangle, you must first be given the other two angle numbers, unless it is an equilateral triangle, in which all angles would equal 60 degrees.
To find the measure of a quadrilateral, you must first be given the other three angle numbers, unless it is a square, in which all angles would equal 90 degrees.
You find the arc measure and then you divide it in half to find the inscribed angle
It will be half the original angle.
Use a protractor

you measure the angel...tehn find the refraction
You find the arc measure and then you divide it in half to find the inscribed angle
Use a protractor.
No cheating!
the measure of the inscribed angle is______ its corresponding central angle
if angle 1 puls angle 5 ewuals 100 find the measure of angle 3
how to find the measure of angle C in the following triangle
The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 degrees.
It will be half the original angle.
You can use various properties of angles to find the measure of the second angle. For example, if you can see that the two angles form a right angle, then you know they add up to 90°, so you can subtract the known measure from 90° to find the measure of the other.
With a protractor
If measure angle 3 = x2 + 4x and measure angle 5 = 3x + 72, find the possible measures of angle 3 and angle 5
If you absolutely needed to measure an angle to find out its degree measure, you would use a protractor.
