This video provides instruction on how to construct an angle bisector for a given angle.

This video contains 1 proof to solve.<br/>
Geometric Proofs, Part 6

👉 Learn how to determine if a given SSA triangle has 1, 2 or no possible triangles. Given two adjacent side lengths and an angle opposite one of them (SSA or ASS), then there are 3 possible cases: there can be 1 solution, 2 solutions,...

This video is a lecture presentation on using circle theorems, with a focus on the chord bisector O. The presenter explains how a circle can be split into two segments by a chord, and how the perpendicular from the center to the chord...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

The video is a tutorial on how to construct bisectors, loci, and identify regions in geometry. The presenter explains the steps to construct a perpendicular bisector with a compass and ruler, as well as how to bisect an angle. The video...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

👉 Learn how to prove that two triangles are congruent. Two or more triangles are said to be congruent if they have the same shape and size. There are many postulates and theorems to determine whether two triangles are congruent. They...

Master finding the missing angle when given an angle bisector

👉 Learn about congruent triangles theorems. Two or more triangles are said to be congruent if they have the same shape and size. There are many methods to determine whether two triangles are congruent. Some of the methods include: (1)...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

Learn how to solve problems with chords. A chord is a line that has its two endpoints on the circle. A chord passing through the center of the circle is refered to as the diameter of the circle. A chord divides the circle into two...

It provides solved problems based on collinearity of points, finding the ratio in which a plane/point divides the segment, points of trisection using section formula.

This video is a lecture presentation on Loci and region. The speaker explains what a locus is and discusses the tools required for solving loci problems, including a ruler, compass, protractors, pens, and pencils. The speaker then goes...
