Number of rays subtracted by one and adding all previous numbers. Example : number of rays : 13 13-1=12 1+2+3+4+5+6+7+8+9+10+11+12=78 there are 78 angles in 13 rays. Or if you were given a sequence pattern. Number of rays. Number of angles. 1-0 2-1 3-3 4-6 5-10 6-? 7-? Get number of rays minus 1 then add it to the previous number of angles. 6-1=5 5 + 10 (number of angles in 5 rays) = 15 7-1=6 6 + 15 (number of angles in 6 rays) = 21 -werty-sama

If the given numbers represent degrees then it is a right angle triangle whos 3 angles add up to 180 degrees.

4 sides and 1 diagonal is given. 3 sides and 2 diagonals are given. 3 angles and measurement of two adjacent angles are given. 3 sides and 2 included angles are given. 4 sides and 1 angle is given.

Supplementary angles are two angles that add up to 180°. Complementary angles are two angles that add up to 90°. Given one of a pair above, subtract it from the sum of the two angles given above.

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.

All the angles of a square are 90 degrees.
