Cyclic Quadrilateral – Proof
2 mins 6th - 12th CCSS: Adaptable
New ReviewWhat do you call a quadrilateral in danger? A peril-lelogram! Scholars avoid danger by proving the opposite angles in a quadrilateral add up to 180 degrees. After viewing a brief video, they complete textbook exercises and a practice...
Angle in a Semi-Circle – Proof
3 mins 6th - 12th CCSS: Adaptable
New ReviewYoung mathematicians observe a geometric proof using a short video. They see each part of the diagram clearly labeled and the simple math written off to the side. The new knowledge helps them solve additional problems independently.
Angles in a Triangle
5 mins 6th - 12th CCSS: Adaptable
New ReviewThe third angle's the charm. Viewers of a short video learn how to find the measure of the missing angle in a triangle. It uses an arithmetic process rather than an algebraic one, so younger learners have no trouble understanding the...
Angles in Quadrilaterals
8 mins 6th - 12th CCSS: Adaptable
New ReviewFour angles hath quadrilaterals, but what be their measures? After watching a video, young mathematicians consider the interior angles of quadrilaterals. They see how to find missing angle measures using the properties of quadrilaterals.
Angles in a Full Circle
5 mins 4th - 12th CCSS: Adaptable
New ReviewCome full circle with a lesson on angles. A noteworthy video describes how to calculate the measures of missing angles in a diagram. It goes through several examples in which the sum of the angles is always a full circle, or 360 degrees.
Position Given Bearings From Two Points
2 mins 6th - 12th
New ReviewGet some directions on how to use bearings with a minute-and-a-half video that shows how to solve a problem using bearings. The narrator gives two points and the bearings of a third point from each point. Scholars must then find the...
Area of a Sector
