Acute angle
It an angle smaller than an right angle (less than 90 degrees)
Obtuse angle
An angle that measures more than 90 degrees but less than 180 degrees .
Right angle
An angle of 90 degrees.
Straight angle
An angle of 180 degrees .
Vertical angle
each of the pairs of opposite angles made by two intersecting lines.
Adjacent angle
Adjacent angles are two angles that have a common vertex and a common side.
Complementary angles
Two angles are complementary if the sum of their measures 90 degrees.
Supplementary angles
Two angles are supplementary if the sum of their measures is 180 degrees.
Corresponding angles
When two lines are crossed by another line.
Transversal
Of a line intersecting a system of lines.
Acute triangle
In an acute triangle, all angles are less than right angles—each one is less than 90 degrees
Right triangle
a triangle with a right angle.
Obtuse triangles
The indicated angle is larger then 90 degrees.
Scalene triangle
A scalene triangle is a triangle that has three unequal sides.
Isosceles triangle
an isosceles triangle is a triangle that has two sides of equal length
Equilateral triangle
A triangle with all three sides of equal length.
