![]() If two angles add up to 180 degrees, they are supplementary. If two angles add up to 90 degrees, they are complimentary. ~- (Two little angles next to each other add up to form one big angle) If two points, rays, or lines divide a segment into three congruent segments, it trisects the segment. ![]() ![]() That is, the measure of the larger angle is the sum of the measures of the two smaller ones. Substitution Postulate: A quantity may be. \(\angle ADC = m \angle ADB \angle BDC\) The Angle Addition Postulate states that: If point B B B is in the interior of A O C angle AOC AOC, then m A O B m B O C m A O C mangle. What is an angle addition postulate in math The angle addition postulate states that if B is in the interior of AOC, then. Addition Postulate: If equal quantities are added to equal quantities, the sums are equal. So, if B is on the interior of \(\angle ADC\), then The angle addition postulate states that if a point is within an angle and you add the two angles that are made by drawing a line through the point that the total will equal the large angle. When two smaller angles form to make a larger angle, the sum of the measures of the smaller angles will equal the measure of the larger angle. Types of Angles acute angles, right angles, obtuse angles, straight angles, reflex angles
