Understanding Parallel, Intersecting, and Perpendicular Lines
In this video, students will learn about parallel, intersecting, and perpendicular lines. They will understand that parallel lines never intersect and are always the same distance apart, while intersecting lines pass through the same point.

Moments _ GCSE Physics
A moment is the turning effect of a force. It’s calculated by multiplying the force by the perpendicular distance between the force and the pivot. For example, by turning a spanner you are producing a moment. If you apply a force of 15N...

What is the definition of a secant line
Learn the essential definitions of the parts of a circle. A secant line to a circle is a line that crosses exactly two points on the circle while a tangent line to a circle is a line that touches exactly one point on the circle. A chord...
