How to find the area of a composite figure khan academy?
isosceles triangle has three sides with equal length. If you have two such triangles, you can find their combined area by adding two smaller triangles that you construct by connecting the vertex of the larger triangle to the base of each of the smaller triangles. This method of constructing the area of an isosceles triangle is known as the Pythagorean theorem. You can use this method to find the area of a right triangle that is formed by two isosceles triangles that share their base
How to find the area of a quadrilateral k
A quadrilateral is a four-sided figure. A regular quadrilateral has four right angles. If you can draw a line segment to connect any two corners on the opposite sides of a quadrilateral, the quadrilateral has four sides. The area of a quadrilateral is equal to the sum of the areas of the triangles formed by the diagonals that connect each pair of opposite corners. If you have a quadrilateral that does not have four right angles, use the
How to find the area of a parabola khan academy?
A parabola has two legs, one of which is a vertex at the focus, the other of which is a direct line segment from the vertex to the directrix. The directrix is the line that the parabola opens towards. If you move the vertex to the other end of the directrix, you'll end up with a symmetrical figure called an equilateral parabola. The area of an equilateral parabola is one-half base × height.
How to find the area of a rectangle khan academy?
One way to find the area of a rectangle is by multiplying the length and width of the rectangle. It can also be found by using the Pythagorean Theorem. The Pythagorean Theorem states that the area of a square is equal to the square of the length of a side multiplied by the square root of the length of the other two sides.
How to find the area of a triangle khan academy?
A triangle has three sides. The area of a triangle equals the length of one base multiplied by the height of the triangle. To find the area of a triangle, you can use the Pythagorean Theorem. If the legs of a right triangle are the length of one base and the length of the hypotenuse, then the area of the triangle is equal to the square root of the sum of the squares of the legs.
