What is a quadrilateral? Squares and rectangles
A quadrilateral is a flat shape, in one plane, defined by four points at the four corners. A quadrilateral has four sides. The sides can be of any length. And it has four corners. They can be at any angle to each other so long as they add up to 360 degrees. A rectangle i... | 677.169 | 1 |

I think you did a great job explaining what a Euler line is. It was especially helpful how you explained the parts of a Euler line in depth. By describing what an orthocenter, circumcenter, and centroid were, it helped me to understand how this line is formed. I ... | 677.169 | 1 |
Are all right triangles Pythagorean triples?
The name is derived from the Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle. However, right triangles with non-integer sides d... | 677.169 | 1 |

This video is part of the Further Maths Units 3 and 4 course and the Measurement and Geometry module. Having taken some time to teach ways to find missing sides and angles using the sine rule, cosine rule and trigonometry, I now look at how these can be applied to some real world situations. I look at what the angles o... | 677.169 | 1 |
To find the orthocenter of a triangle, you need to find the point where the three altitudes of the triangle intersect. An altitude is a line segment from a vertex of the triangle perpendicular to the opposite side.
First, find the slopes of the lines containing the sides of the triangle. Then, determine the slopes of ... | 677.169 | 1 |
Measure angle.
An angle that is exactly 90 ∘ (one quarter of a circle) is called a right angle. A right angle is noted with a little square at its vertex. An angle that is more than 90∘but less than 180 ∘ is called an obtuse angle. An angle that is …

What are Geometries in Spatial Computing?
In augmented reality (A/R), virtual reality (V/R) and mixed reality (M/R), the term "geometry" (plural: "geometries"), refers to a three-dimensional (3D) shape that has three dimensions: length, width and height. | 677.169 | 1 |
Solution:
Geometric shapes with diagonals come in many different shapes. Parallelogram, square, rectangle, rhombus, etc. However, the state of the photo frame requires the diagonal lengths to be different. The length of the diagonals of a square and a rectangle are the same. So they are not the solution. The diagonals... | 677.169 | 1 |

Solution:
Given that ∆ABC is right angled at C. According to the angle sum property of a triangle say ABC, it can be represented as ∠A+∠B+∠C=180°Since ΔABC is a right-angled triangle at C means ∠C=90° . Substitute 90° for ∠C in ∠A+∠B+∠C=180°∠A+∠B+∠C=180° ⇒∠A+∠B+90°=180°⇒∠A+∠B=180°−90°⇒∠A+∠B=90°Take both sides cosine i... | 677.169 | 1 |
