Cones: The union of the line segments connecting a point P with each point of a simple, closed curve, the simple, closed curve in the interior of the group

Classifications of Polygons:

Polygon: all sides are congruent and all angles are congruent

Right triangle: a triangle in which all the angles are acute.

Acute triangle: a triangle in which all the angles are acute

Obtuse triangle: a triangle containing one obtuse angle

Scalene triangle: triangle with no congruent sides

Isosceles triangle: a triangle with at least two congruent sides.

Kitequadrilateral with two adjacent sides congruent and the other two sides are also congruent.

Trapezoid: a quadrilateral with at least one pair of parallel sides.

Isosceles trapezoid: a trapezoid with congruent base angles.

Parallelogram: a quadrilateral in which each pair of opposite sides are parallel.

Rectangle: a parallelogram with a right angle.

Supplementary: the sum of the measure of two angles is 180 Complimentary angles: the sum of the measures of two complementary angles is 90 degrees Congruent angles: all angles are the same Vertical angles: a pair of angles whose sides are two pairs of opposite rays Corresponding angles: have the same angle measures in degrees Classification of angles: types of angles include acute, obtuse, right and straight angle. Angles can also be adjacent or vertical Angle: a figure formed by two rays

Surface Area

Surface area of Prism
2(base x height) + 2(length x base) + 2(length x height)

When doing a triangular prism it is half of t

Surface area of Prism
2(base x height) + 2(length x base) + 2(length x height)

When doing a triangular prism it is half of the formula

Surface area of Cylinder
2πr² + 2πrh

When sliced you must add the surface area
of the side it is sliced on

Surface area of Cylinder
2πr² + 2πrh

When sliced you must add the surface area
of the side it is sliced on

Surface area of sphere
4πr²

for a hemisphere you must add the face it looks sliced on

Surface area of sphere
4πr²

for a hemisphere you must add the face it looks sliced on

Pythagorean Theorem

a² + b² = c²
Only works for right triangles
Atleast one angle must be 90 degrees

If.. a² + b² ≠ c² then it is not a right tr

a² + b² = c²
Only works for right triangles
Atleast one angle must be 90 degrees

If.. a² + b² ≠ c² then it is not a right triangle
and pythagorean thereom does not work
