Watch Mr. Almeida explain the formula for the area of a triangle. See if you can see why the formula for area of a triangle is A=1/2 x b x h. Think about first, and then continue to read for the answer. The formula for area of a triangle is so because a triangle is 1/2 of a rectangle. Try drawing a triangle and then draw dotted lines going for another height going from the base. If it a right triangle, connect the parallel length on top with a dotted line. Do you see a rectangle? The triangle is half of that. That is why the formula works. This illustrates Common Core math standard 6.G.1.
6.G.1 - Area of a Triangle is a free educational video by MathwithMrAlmeida.It helps students in grades 6 practice the following standards 6.G.A.1.
1. 6.G.A.1 : Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems..
