Scalene Right

One angle equals 90 degrees all the other angles are diffrent

Obtuse scalene

One angle is greater than 90 degrees

Here

This is a math problem

Points of Concurrency

Acute Scalene Triangle

All angles are different and less than 90 degrees

Equilateral Triangles

All sides are equal

These two triangles are congruent by AAS

triangle ABC is congruent to FED

Angle ABC is to Angle FED

Conditional Powerpoint

solved this angle by adding together angle 2x-11 and angle 51 and = to 90 because the whole angle equals

Two perpendicular angles

Complementary angles

1)Distance formula for the points (-4,3) and (6,-2)

2)Substitute the point the formula if any numbers are negative rember to keep up with the signs
3)add and subract the numbers
4)square the number,this will always be a positive number
5) add your squares
6)approximate using calculator
7)simplify to 5 on the square root 5

supplentary angle

angle ABC is Complementary to angle FED and DEF is Supplementary

8/27 miscellaneous angle info 2

angle abc and cbd are supplentary they also adjancent so they form a linear pair the sum of these are 180 degrees

8/27 miscellaneous angle info

They are two complanetary angles that add up to be 90 degrees

Whatz up

math is awsome

What NOW!!!

Math is Freakin AWSUM!!!
