When we want to write the equation of a line perpendicular to another through a point we need to make sure that identify the correct slope as well as the equation of a line.



⭐️ Writing equations of a Line parallel through a...

You could say that angles are some of the building blocks of geometry, and you've probably already seen lots of examples of angles in your life already. In this lesson, we'll go over the exact definition of an angle, how to name an...

When you hear the word "geometry", you might think of shapes. And you wouldn't be wrong! But before we can get to shapes, we need to talk about the parts that can make up shapes, like points, lines, rays, and line segments. In this...

At this point we know a lot about how rocks form, but now we need to understand precisely how they are weathered. Weathering describes the forces and conditions that break down rocks that are exposed at the surface into smaller...

In this video, the teacher explains how to write and create equations of lines using slope. They discuss parallel and perpendicular lines and provide examples and explanations for each concept.

Wave Motion demonstrates the difference between transverse and longitudinal waves in terms of motion and energy.

This video explains geometrical representation.<br<br/>/>

This clip is from the chapter "Linear Regression Analysis" of the series "R Programming for Statistics and Data Science".This section explains linear regression analysis.

My solutions to Free Response Question #2 from the 2017 AP Physics 1 Exam. Also included are my reflections on how to get more points on the exam.

This Experimental Design question also works as a part of the AP Physics C:...

In this lesson, students will learn how to find the circumcenter and incenter of a triangle using angle bisectors, perpendicular bisectors, and circles. They will understand the concept of different centers in a triangle and how they...

In this video, you will learn how to construct an inscribed circle on a triangle using the triangle's angle bisectors. The inscribed circle is the largest possible circle that fits inside the triangle, with the triangle's sides tangent...

A 0.453 kg toy car moving at 1.15 m/s is going up a semi-circular hill with a radius of 0.89 m. When the hill makes an angle of 32° with the horizontal, what is the magnitude of the force normal on the car?

In this video, students will learn how to predict the three-dimensional shape that results from rotating a two-dimensional figure. By analyzing the effects of rotations and understanding the concept of an axis of rotation, they will be...

Why is it important to do proofs? What is a proof? Why does every statement have to be true?<br/>
Geometric Proofs, Part 1

This video goes over the dot product also known as the scalar product. This video goes over 5 examples illustrating how to solve problems that make use of the geometric and component definition of the dot product.

👉 Learn how to evaluate the secant of the sum or difference of two angles using the sum/difference formulas. To do this, we first use the Pythagoras theorem to obtain all the sides of the right triangle in the unit circle. Recall that...

We just learned about the different types of rock deformation, so now let's get a closer look at some more specific structures. First we have faults, which can be normal, reverse, and strike-slip or reverse faults. We should also take a...

Calculus based review of Newton’s three laws, basic forces in dynamics such as the force of gravity, force normal, force of tension, force applied, force of friction, free body diagrams, translational equilibrium, the drag or resistive...

This is a lecture video on moments, which explains what a moment is and how to calculate the moment of a force. The video uses various examples to illustrate the concept of moments and how they are affected by the magnitude and direction...

In this video, students learn how to describe the cross-sections of a right rectangular pyramid by slicing at different angles. They are introduced to the concept of cross-sections and how they result from cutting a 3-dimensional shape...

In this online video we will learn how to find the Area of triangle in Coordinate Geometry and simple trick to remember the formula quickly.

In this video lesson, we explain the concept of perpendicular lines and demonstrate how to identify them in different shapes. By the end of the lesson, students will be able to categorize polygons based on the number of pairs of...

It's not enough to just consider the number of sides in a quadrilateral, we must also consider the congruence of sides, the types of angles formed, and the presence of parallel or perpendicular lines. Using a square as an example, we...
