Please check the visualization of the area of a triangle in coordinate geometry. Plane Geometry is for shapes such as triangles circles rectangles square geometry formulas and much more. The area of the triangle is the space covered by the triangle in a two-dimensional plane.
Solid Geometry deals with calculating the perimeter length area and volume of different geometric figures and shapes.
The vertical bars mean you should make the reult positive even if it calculates out as negative. Using 00 as the center of dilation and a scale factor of 2 draw the dilation image and state the coordinates of each vertex of the image. As an example to find the area of a triangle with a base b measuring 2 cm and a height h of 9 cm multiply ½ by 2 and 9 to get an area of 9 cm squared.
