Area of a TriangleAuthor:Thomas, Adam AntonioTopic:AreaEstablish the formulas for areas of rectangles, triangles and parallelograms, and use these in problem solving (ACMMG159 - Scootle) - building on the understanding of the area of rectangles to develop formulas for the area of triangles - establishing that the area of a triangle is half the area of an appropriate rectangle - using area formulas for rectangles and triangles to solve problems involving areas of surface Use the sliders (red dots) to change the size of the triangle/rectangle. Use the checkboxes (top left-hand corner) to show/hide the area of the rectangle and triangle. Use formula: B x H (base x height) for surface area of a rectangle. Use formula: 1/2 B x H (half [0.5] x base x height) for surface area of a triangle. GeoGebraCan you see the relationship between the area of a triangle and a rectangle? (50-100 words) Find the area of both rectangle and triangles for: a) B = 6, H = 4 Rectangle Area = Triangle Area = b) B = 12, H = 10 Rectangle Area = Triangle Area = c) B = 20, H = 50 Rectangle Area = Triangle Area = Use the interactive platform to make and solve 5 of your own problems (you can be creative with your numbers). a) b) c) d) e)
