Geometry

Reference Table for Solids

Volume is measured in cubic units. Surface area is measured in square units.

Volume (V) and Surface Area (SA) FormulasNote:  Surface area formulas may need to be amended if the figure has "open" surfaces,
such as when working with a box without a lid or with an empty paper towel roll.

	Rectangular Solid V=lwh SA=2lh + 2hw + 2lwThis formula assumes a "closed box", with all 6 sides.
	Cylinder This formula assumes a "closed container", with a top and bottom..
(optional formula)	Sphere
(optional formula)	Cone This formula assumes a "closed container", with a bottom..

Geometry

Circles and Chords

A chord is a segment that joins two points of the circle. A diameter is a chord that contains the center of the circle.

Theorems:

1.2. 3.

In a circle, a radius perpendicular to a chord bisects the chord.In a circle, a radius that bisects a chord is perpendicular to the chord. In a circle, the perpendicular bisector of a chord passes through the center of the circle.

Proof of Theorem 1:

Statements		Reasons
1.		1.	Given
2.		2.	Two points determine exactly one line.
3.		3.	Perpendicular lines meet to form right angles.
4.		4.	A right triangle contains one right angle.
5.		5.	Radii in a circle are congruent.
6.		6.	Reflexive Property - A segment is congruent to itself.
7.		7.	HL - If the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.
8.		8.	CPCTC - Corresponding parts of congruent triangles are congruent.
9.	E is the midpoint of	9.	Midpoint of a line segment is the point on that line segment that divides the segment two congruent segments.
10.		10.	Bisector of a line segment is any line (or subset of a line) that intersects the segment at its midpoint.

 

Theorem:

In a circle, or congruent circles, congruent chords are equidistant from the center. (converse) In a circle, or congruent circles, chords equidistant from the center are congruent.

Theorem:

In a circle, or congruent circles, congruent chords have congruent arcs.(converse) In a circle, or congruent circles, congruent arcs have congruent chords.

;

Theorem:

In a circle, parallel chords intercept congruent arcs.
