Accelerated Math 2
Two minor arcs are congruent if and only if their corresponding chords are congruent.
Remember: A tangent is perpendicular to the radius Also, if two tangents start at the same point, then they are congruent.
If one chord is a perpendicular bisector of another chord, then the first chord is a diameter. All of the following congruencies will be true:
Arc Length is a partial circumference Arc Length differs from Arc Measure in that it is measured in units (cm, ft, in……) Arc Measure is measured in degrees Formula:
Usually a shaded area, like a slice or multiple slices of pizza Sector Area is a partial area Formula:
Circumference Arc Radius Diameter Chord Tangent Segment Sector
Circles Review Unit 9.
Section 10-2 Arcs and Central Angles. Theorem 10-4 In the same circle or in congruent circles, two minor arcs are congruent if and only if their corresponding.
Unit 3: Circles & Spheres
6.3 – 6.4 Properties of Chords and Inscribed Angles.
10.3 – Apply Properties of Chords. In the same circle, or in congruent circles, two ___________ arcs are congruent iff their corresponding __________.
CIRCUMFERENCE: or If you unwrap a circle, how long will the line be?
Chord and Tangent Properties. Chord Properties C1: Congruent chords in a circle determine congruent central angles. ●
1. 3x=x y+5y+66= x+14x= a 2 +16=25 Note: A diameter is a chord but not all chords are diameters.
Chapter 7 Circles. Circle – the set of all points in a plane at a given distance from a given point in the plane. Named by the center. Radius – a segment.
11.5 Sectors and Arc Lengths
Section 10.2 – Arcs and Chords
Applied Math II
Radius diameter secant tangent chord Circle: set of all points in a plane equidistant from a fixed point called the center. Circle 4.1.
Circles and Chords. Vocabulary A chord is a segment that joins two points of the circle. A diameter is a chord that contains the center of the circle.
Main Idea 1: If the arcs are congruent, then the chords are congruent. REVERSE: If the chords are congruent, then the arcs are congruent. Main Idea 2:
Area Circumference Sectors
Chapter 10.3 Notes: Apply Properties of Chords
RECALL: What is the formula for the area of a circle? You eat an entire pizza (8 slices) with a radius of 8inches. How much pizza (area) did you eat? If.
