Opening slide reviews the angles in right, obtuse, and acute triangles. Lecture includes and introduction to medians and altitudes. Last slide is for students to try try to draw their own medians and altitudes. Slides are animated.

7 animated slides, including title slide. Opener slide includes using algebra to solve a word problem referring to complements and supplements. Lecture includes the properties of adding and subtracting segments and angles. There is an opportunity for students to apply what they learn to understand the last subtraction property.

8 animated slides, including title slide. Opener slide includes algebra review using 180 degree angles and perpendicularity. Lecture includes the definition of undefined terms, definitions and theorems. It also includes complementary and supplementary angle problems using algebra. There are examples for students to work on applying these ideas.

7 animated slides. Opening problem is an intro and very loose proof to the right angles theorem. Lecture slides include the definition of a perpendicular bisector, the perpendicular bisector theorem, and its converse (the equidistance theorem). It also includes a hint on how to tell the difference between the 2 theorems and a practice proof.

6 animated slides. Lecture includes an intro vocabulary. Also, the 4 different ways to make planes and 2 postulate about the intersection of lines and planes. Lastly, this ppt includes an activity for students that I find very helpful. Each student needs 2 index cards to construct a 3D visual of the intersection of 2 planes. The students will use the planes to answer questions on the last slide. These index cards can be referred back to throughout the unit.

Powerpoint starts with an opener reviewing naming corresponding congruent parts in triangles. Lesson includes introduction to SSS postulate, SAS postulate, and 2 examples.

Opener to lesson includes review of angles in right, acute, and obtuse triangles. Also, a short, hands-on proof of the base angles theorem for students to try on their own. Lecture includes introduction to base angles theorem, the converse of the base angles theorem, a fill in the blank proof of the base angles theorem, and an application of the BA theorem. Also, an introduction to the hypotenuse leg theorem.

7 animated slides. Opener slide includes review of ratios and cross multiplying. Lecture includes the definition of ratios, proportions, means, extremes, and the geometric mean. It also includes the means-extremes theorem (cross-multiplying) and its converse. There are also examples for students to work on applying these ideas.

8 slide introduction to angle bisectors, angle trisectors, segment bisectors and trisectors, and midpoints. There are example applications with algebra. Also includes a challenge problems at the end for students to work on with partners or small groups. Slides include animation.

7 animated ppt slides including title slide and opener Opener reviews median, quartiles, and IQR Intro to mean, measures of dispersion: range and standard deviation Includes excel formulas and calculating standard deviation using a table Last slide is a homework problem

Powerpoint includes introduction to exterior angles theorem, the 3rd angle theorem, a definition of congruent figures, reflexive property, and how to write congruency statements.

Quiz is a half sheet, front and back. It prints two sided, then you can cut in half. Assesses student understanding of exterior angle theorem, the 3rd angle theorem, congruent figures, and how to write congruency statements.

6 animated slides. Opener slide includes review of straight and right angles. Lecture includes the definition of undefined terms, postulates, definitions and theorems. It also includes the conditional statements (if-then) and converse statements. There are examples for students to work on applying these ideas.

Intro to measuring segments and angles and congruency. Examples and discovery activity included.
