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

What statements are true about a 30 60 90 triangle?
If the given numbers represent degrees then it is a right angle triangle whos 3 angles add up to 180 degrees.
What makes a quadrilateral unique?
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.
What is the difference between supplement and complement?
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.
How do you find the measure of angle?
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.
How do you find the missing angle of a square with no given angles?
All the angles of a square are 90 degrees.
Do you see any pattern in determining the numbers of subsets of a given set?
A set with n elements has 2^n subsets.
How do you find the measure of an angle in a triangle?
Add together the given angles, or the angles you already know or have been given measures for, and then subtract the added numbers from 180 and that is you answer.
How do you determine the number of angles of a polygon given the number of sides?
The two numbers are the same.

Given triangle ABC is conguent to triangle DEF AB15 BC20 AC25 and FE 3x-7 find x?
Re-check your question because the degrees of the angles cannot be the numbers given.
How do you calculate unknown angles?
You use the information you're given, along with the rules, equations and formulas you know that relate the given information to the unknown angles, to find the angles.
What is the difference between supplement and complement?
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.
What is the name given to angles which add up to 90 degrees?
right angles
The angles of a triangle that are not adjacent to a given exterior angle?
Remote interior angles
What is the name given to angles that measure between 0 and 90?
Acute angles
