3 days ago · This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the Pythagorean theorem to find the length of the hypotenuse or a leg of a right triangle and its area.
1 day ago · \( A_{\text{triangle}} = \frac{ b \cdot h}{2}, \) where \(b\) is the base and \(h\) is the height. Plugging in their values, we have \( \frac{ 5 \times 5}{2} .\) Since there are 2 triangles, we multiply it by 2 to obtain
3 days ago · In this explainer, we will learn how to find the projection of a point, a line segment, a ray, or a line on another line and find the length of the projection.
5 days ago · The surface area of a regular tetrahedron is four times the area of an equilateral triangle: [6] The height of a regular tetrahedron is . [7] The volume of a regular tetrahedron can be ascertained similarly as the other pyramids, one-third of the base and its height.
1 day ago · In this lesson, we will learn how to find the area of a triangle using the lengths of two sides and the sine of the included angle.
5 days ago · The slant height (L) is calculated using this formula: \ [ L = \sqrt {H^2 + \left (\frac {S} {2}\right)^2} \] where: \ (L\) is the slant height, \ (H\) is the center height, \ (S\) is the side length. Example Calculation. To calculate the slant height: Suppose the center height (\ (H\)) is 8 units, and the side length (\ (S\)) is 6 units.
4 days ago · The area (\(A\)) of an inscribed triangle is calculated using Heron's formula: \[ A = \sqrt{p(p - a)(p - b)(p - c)} \] where \(p\) is half the perimeter of the triangle (\(\frac{a + b + c}{2}\)), and \(a\), \(b\), and \(c\) are the lengths of the sides of the triangle.
