Adding and Subtracting Angles: 4.MD.7


By TenmarksAmazon

Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems

Vertical angles


By Khan Academy

By using our knowledge of supplementary, adjacent, and vertical angles, we can solve problems involving the intersection of two lines. Including this one!

Unknown angle algebra problems


By Khan Academy

Solve this word problem to find the measure of angles. In this example you'll split up a pie (don't forget to share!)

Find missing angles of triangles


By Khan Academy

Sal solves the following problem: The measures of two angles of an isosceles triangle are 3x+5 and x+16. Find all possible values of x.

This lesson covers complementary angles. Students learn the definition of complementary and supplementary angles, as well as how to find the measures of the complement and supplement of a given angle. Students are also asked to solve word problems in the following form: "If the ratio of an angle to its complement is 2:3, find the measure of each angle."

This lesson covers the sum of the interior angles of a polygon. Students learn the definitions of vertices and diagonals of polygons. Students also learn the following formulas related to convex polygons. The sum of the measures of the interior angles of a polygon is always 180(n -- 2) degrees, where n represents the number of sides of the polygon. The sum of the measures of the exterior angles of a polygon is always 360 degrees. Students are then asked to solve problems using these formulas.

This lesson covers the properties of a rhombus. Students learn the definitions of a rectangle, a rhombus, and a square. Students also learn the following theorems. The diagonals of a rectangle are congruent. The diagonals of a rhombus are perpendicular and bisect the angles of the rhombus. The midpoint of the hypotenuse of a right triangle is equidistant from the three vertices. Students are then asked to solve problems related to these concepts using Algebra.

Banked turn Physics Problems


By The Organic Chemistry Tutor

This physics video tutorial provides plenty of practice problems on banked turns without friction. It explains how to set up the free body diagram to solve banked curve problems and how to derive the formula to calculate the speed of a car and the banking angle without static friction and how to calculate the minimum speed and the maximum speed that a car can travel without sliding up or down the banked curve as well.
