What are the properties of quadrilaterals?

In geometry, the parallelogram and the trapezoid are the fundamental quadrilaterals respectively to classify their own type. The types of parallelograms are the rectangle, rhombus, and square. The types of the trapezoid are the isosceles trapezoid and a right trapezoid.

Triangle Proofs

In triangle proofs, we try to prove two triangles to be congruent based on the five main theorems alongside with some other statements to fill out or given. However, they are two triangle theorems that are known as “donkey theorems” because the two triangles are not congruent.


When you are working with angles in geometry, the main shapes we dealt with is triangles, squares, and circles. If you have a circle, all the angles add up to 360 degrees, triangles are 180 degrees, and squares are 360 degrees.

Intro to exponents

Remember exponents? In pre-algebra you work with the letter x/y that represents a number. We can have x/y given to us and you plug the number into the problem and solve or you have to solve it algebraically. You may have to simplify the problem to get an exponent. This is what we will be…

Pythagorean Theorem

In this problem, the student will be give two distances as two sides of a triangle, and will need to use the Pythagorean Theorem to calculate how far a woman lives from her workplace. The Pythagorean Theorem is a formula used to determine the length of one side of a triangle if two of the…

Triangle Inequalities: Can it Make a Triangle?

There are rules that triangles must follow. One of these rules is that the sum of the lengths of any two sides of a triangle is greater than the length of the 3rd side. In other words, whenever you add the length of two sides of a triangle together, it must equal more than the…

Trig Table.

Trigonometry allows us to use ratios that are associated with any angle ABC, so we can calculate a broad range of heights without having to measure them. You will learn about three important ratios for any angle: sine (shortened to sin), cosine (cos) and tangent (tan).

Area of Triangle: Real World Situations

In this tutorial, we’re going to look at a real world solution for finding a missing base or height when given the area of a triangle and either a given base or height.

Finding the Area of a Triangle

In this tutorial, I will be showing you how to find the area of a triangle.
