Volume of Pyramid

"The formula for the volume of prisms can also be applied to the volume of pyramids, which occupy only one third of the space of a corresponding prism with the same base and height. To calculate the ...

Volume of Cylinder

"The prism volume formula of height times the area of one of the bases can also be applied when calculating the volume of cylinders. To find the volume of a cylinder we simply multiply the height of ...

Volume of Cone

"The formula for the volume of cylinders can also be applied to the volume of cones, which occupy only one third of the space of a corresponding cylinder with the same base and height. To find volume ...

Vertices

"The plural form of vertex, vertices are typically intersections or corners in figures. In an angle, the vertex is where two lines, rays, or segments meet. A diagonal is a line segment whose endpoint ...

Vertical Angles

"Vertical angles always come in pairs. They share a common vertex but they cannot share a side. Vertical angles are congruent, which means they have equal measures." Fuente: BrightStormVertical Angl ...

Kite Properties

"Knowing the properties of a kite will help when solving problems with missing sides and angles. Kite properties include (1) two pairs of consecutive, congruent sides, (2) congruent non-vertex angles ...

Using Sine to Calculate the Area of a Triangle

"Using the standard formula for the area of a triangle, we can derive a formula for using sine to calculate the area of a triangle. Using sine to calculate the area of a triangle means that we can fin ...

Using a Protractor

"In Geometry, it is important to know how tomeasure an angle. Using a protractor helps us determine the angle measurement so we can label it as acute, right or obtuse. Every protractor is a little bit ...

Isosceles Triangle Properties

"In isosceles (and equilateral) triangles, a segment drawn from the vertex angle to the opposite side is the altitude, angle bisector and median. Isosceles triangle properties are used in many proofs ...

Isosceles Triangle

"Isosceles triangles have at least two congruent sides and at least two congruent angles. The congruent sides, called legs, form the vertex angle. The other two congruent angles are the base angles. I ...
