Special Right Triangles in Geometry: 45-45-90 and 30-60-90
By PatrickJMT
Special Right Triangles in Geometry: 45-45-90 and 30-60-90 degree triangles. In this video, I discuss two special right triangles, how to derive the formulas to find the lengths of the sides of the triangles by knowing the length of one side, and then do a few examples using them!

Inscribed Angles - YourTeacher.com - Geometry Help
By yourteachermathhelp
Students learn the definition of an inscribed angle, and that the measure of an inscribed angle is equal to ½ the measure of its intercepted arc. Students also learn the following theorems related to inscribed angles. If two inscribed angles intercept the same arc, then the angles are congruent. An angle inscribed in a semicircle is a right angle. If a quadrilateral is inscribed in a semicircle, then opposite angles are supplementary. The measure of an angle formed by a chord and its tangent is half the measure of the intercepted arc. Students are then asked to find the missing measures of arcs and angles in given circles using these theorems.
How to Apply Postulate 13 to Similar Triangles
By Khan Academy
Video uses an electronic black board with different colored pens. This video is an introduction to similar triangles. The person discusses the meaning of the term similar then goes on to discuss similar triangles (they have all the same angles), and why they are considered similar (ratio of corresponding sides is the same). Video then gives examples to help students understand the terms used and how to find similar angles. Good quality video. Good for middle elementary and middle school students.

Similar Triangles, Part 2 - Khan Academy
By Khan Academy
Video uses an electronic black board with different-colored pens. In this video. Mr. Khan discusses the measurement of alternate interior angles, corresponding angles and how they are similar. Triangles are drawn in two parallel lines and a transversal. Narrator shows how to figure out the length of the sides of the angles when three sides are known. Good quality video. Good for middle elementary and middle school students.

45-45-90 triangles | Right triangles and trigonometry | Geometry | Khan Academy
By Khan Academy
Video uses an electronic black board with different colored pens. Introduction to 45-45-90 Triangles, these can also be called right triangles because of the 90 degree measurement. These triangles are special because if two angles of a triangle are equal the one side they don’t share is going to be equal. This then goes on to explain Pythagorean Theorem, Side A squared + Side B squared = Side C squared, side C is the hypotenuse or the side that is shared in a triangle. The narrator goes on to explain how to solve, using square roots. This video is for middle school students.
