#### SAT Prep: Test 8 Section 8 Part 2

One of Sal's greatest gifts to students in this SAT video series has been his demonstration of word problems. Because he writes out equations while simultaneously reading the information provided, he often arrives at the correct answer...

Lesson Planet: Curated OER

#### Unit 11 Review: Circles

Solve problems around a circle. Pupils watch a video that shows how to apply concepts about circles and related angles and segments to find solutions to word problems. Learners then review the different concepts from the unit in...

Lesson Planet: Curated OER

#### Secants and Tangents

Put the vertex in, put the vertex out. Pupils explore theorems about the relationships of lengths of segments and angles of line segments that intersect inside or outside the circle. Learners use the theorems to solve problems involving...

Lesson Planet: Curated OER

#### Intercepted Arcs

Intercept the class's learning on circles. Pupils learn the relationship between intercepted arcs and inscribed angles. The scholars use that information to find the relationship of angles in an inscribed quadrilateral and an angle...

Lesson Planet: Curated OER

#### Chords and Arcs

Congruence breeds congruence. Pupils learn three more circle theorems dealing with congruent chords and arcs. Learners use the theorems to find the measures of chords and arcs in circles by applying previously learned concepts in the...

#### Marking Starting Locations for the 400-Meter Dash Track and Field Event

No fair! I had to run more than they did! Young mathematicians first measure various lengths on a school track. They develop strategies and show calculations to prove that all participants will run the same length using a staggered...

Lesson Planet: Curated OER

#### Angles in the Same Segment – Proof

If angles intercept the same arc, the angles must be the same size. The quick video talks through the proof of showing the reason two inscribed angles that intersect the same arc have the same measurement. Pupils then create their own...

Lesson Planet: Curated OER

#### Module 5: Circles A Geometric Perspective

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Lesson Planet: Curated OER

#### Angles Outside a Circle: Lesson

Understand the difference in finding angle measures. A segment of an extensive geometry playlist introduces the formula to find the measure of an angle formed outside of a circle. Using examples, the video shows how to calculate measures...

Lesson Planet: Curated OER

#### Inscribed Angles in Circles: Lesson

Circle the angles and intercept the arcs. The video introduces three theorems relating to inscribed angles in circles. Using drawings, the segment of a playlist on geometry illustrates the measure of angle along with theorems about two...

Lesson Planet: Curated OER

#### Measuring Arc Length: Lesson

Slice off a piece of pi! A section of an extensive playlist on geometry develops the formula to find the length of an arc. Using the formula, the presentation works through examples finding the arc length, the radius, and the measure of...

Lesson Planet: Curated OER

#### Angles On and Inside a Circle: Lesson

A video introduces methods to find the measure of angles whose vertex is on and inside a circle. Within examples, the section of a larger playlist on basic geometry incorporates several angle measurement theorems.

Lesson Planet: Curated OER

#### Arcs in Circles: Lesson

Taking a major look at arcs is not minor. A segment of an extensive playlist on geometry introduces the concept of an arc in a circle. The resource demonstrates how to find the measure of an arc and defines special types of arcs.

Lesson Planet: Curated OER

#### Chords in Circles: Lesson

Strike a chord with four theorems. The segment of a playlist on geometry introduces four basic theorems about chords in a circle. Theorems include the relationships between diameters and chords, congruent chords and arcs, and congruent...

Lesson Planet: Curated OER

#### Angle Basics

Take a linear approach to acquaint the class with angles. The video introduces the idea of angles from the notion of intersecting lines. Using the idea of perpendicular lines, the resource defines right, acute, and obtuse angles along...

Lesson Planet: Curated OER

#### Arc Length and Area of a Sector

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...
