All the Cross-Sections of a Cylinder

All the Cross-Sections of a Cylinder

Cylinder cross-sections are obtained when we cut a cylinder with a plane. Depending on the orientation of the plane, a cylinder can form three different cross-sections. If the plane is parallel to the bases, we get a circular cross-section. If the plane is...

Nets of a Cylinder – Diagrams and Characteristics

The geometric net of a cylinder is a two-dimensional pattern or a 2D figure that can be folded to form a three-dimensional cylinder. The net of a cylinder consists of two circular bases and a rectangle, which forms the lateral surface of the cylinder. Here, we will...

Nets of a Cone – Diagrams and Characteristics

The net of a cone is a 2D shape or a 2D pattern that can be folded to form a 3D shape, in this case, a cone. The net of a cone consists of a circular base and a curved surface that forms the lateral surface of the cone. Here, we will look at the diagrams of the net of...
Converse of the Pythagorean Theorem – Formulas and Examples

Converse of the Pythagorean Theorem – Formulas and Examples

The Pythagorean theorem is the most used in trigonometry and allows us to calculate the length of one of the sides of a triangle if we know the length of the other two sides. On the other hand, the converse of the Pythagorean theorem allows us to determine whether a...
Vertical Angles Theorem – Definition, Proof and Examples

Vertical Angles Theorem – Definition, Proof and Examples

Vertical angles are formed at the intersection of two lines. The vertical angles theorem tells us that the vertical angles formed at an intersection are equal. Also, a vertical angle and its adjacent angle are supplementary angles since they add up to 180 degrees....
Vertical Angles Theorem – Examples and Practice Problems

Vertical Angles Theorem – Examples and Practice Problems

The vertical angle theorem tells us that the pairs of vertical angles formed by the intersection of two lines have the same size. In this article, we will look at a summary of the vertical angles theorem. Then, we will apply this theorem by solving various practice...
