Geometry Notes and Help
: The naming of an angle is related to the line segments that create it. We'll also learn about the angle's vertex. Come on. Let's do this.
Complementary and supplementary angles
: Let's add some tools to our geometry tool belt. Here's a thorough explanation of complementary and supplementary angles, as well as definitions of adjacent and straight angles.
Introduction to vertical angles
: By using our knowledge of supplementary, adjacent, and vertical angles, we can solve problems involving the intersection of two lines. Including this one!
Solving for an angle
: Let's use a little math with our geometry and see if we can solve for a mystery angle. In this example we know the adjacent angle AND the combination of the mystery angle and the adjacent angle. Mystery angle...how big are you?
Triangles: categorization by angle or equal sides.
: Scalene, isosceles, equilateral, acute, right, obtuse. All are types of triangles but what makes them special depends on the method of categorization. Watch this outstanding explanation.
Circles: radius, diameter, circumference and Pi
: Learn how the number Pi allows us to relate the radius, diameter, and circumference of a circle.
Area of a circle
: In this example, we solve for the area of a circle when given the diameter. If you recall, the diameter is the length of a line that runs across the circle and through the center.
Area of a shaded region
: Here's a fun one: find the area of a shaded region where you first determine the area of a square and then the area of a circle.
