Unit Five: Geometry
Supplementary Angle(s)
When adding up to 180 degrees (which makes a straight line), makes a supplementary angle. Adjacent Angle(s)
Are angles that are side by side and share a ray. Triangle Sum Theorem
The theorem shows that when summing the measures of the intersecting angles of a triangle will equal 180. (It has to be 180, to be a triangle.) Parallel Plane(s)
Parallel Planes are planes that never intersect each other. Isosceles Triangle
A Isosceles triangle has two congruent sides(not all!). Triangle Inequality Theorem
The sum of the two sides in a triangle can not be larger than the other number in all three measures. Volume
The capacity of cubic units it takes to fill in 3D shape. Perpendicular Plane(s)
A intersect at a right angle. |
Complementary Angle(s)
When adding up to 90 degrees (which makes a right angle), makes a complementary angle. Vertical Angle(s)
A vertical angle is two non-adjacent congruent angles that are formed by two intersecting lines. Cross Section
When a 3D shape is sliced it makes a 2D shape in it. Plane
A flat quadrilateral. Scalene Triangle
A scalene triangle has all different side lengths (none of the measures in the triangle are the same). Equilateral Triangle
A equilateral triangle has all congruent sides on a triangle. Surface Area
The total area of all faces in a 3D shape. Net
A layout of a 3D shape in 2D form. |
