For a complete lesson on proving triangles are congruent, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn the following postulates related to congruent triangles and triangle proofs. If the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent (Side-Side-Side or SSS). If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent (Side-Angle-Side or SAS). If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent (Angle-Side-Angle or ASA). Students are then asked to determine whether given triangles are congruent, and name the postulate that is used.

This lesson covers dividing integers. Students learn to divide integers using the following rules. A positive divided by a positive equals a positive. For example, +20 divided by +2 = +10. A positive divided by a negative equals a negative. For example, +20 divided by -2 = -10. A negative divided by a positive equals a negative. For example, -20 divided by +2 = -10. And a negative divided by a negative equals a positive. For example, -20 divided by -2 = +10. In other words, if the signs are the same, the quotient is positive, and if the signs are different, the quotient is negative. Note that any integer divided by zero is undefined. For example, +4 divided by 0 = undefined. And zero divided by any integer (other than zero) is zero. For example, 0 divided by +4 = 0.

This lesson covers the hypotenuse leg and angle angle side theorems. Students learn the third angle theorem, which states that if two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. Students also learn the following theorems related to congruent triangles. If two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another triangle, then the triangles are congruent (Angle-Angle-Side or AAS). If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the triangles are congruent (Hypotenuse-Leg or HL). Students are then asked to determine whether given triangles are congruent, and name the postulate or theorem that is used.
