Find slope of CB and then the negative reciprocal of that will be the slope of the height. With those slopes we can make them into equations and use the

Find equation of CB and the slope of the rp

Using the length formula to find the length of all sides. And then use the formula to find the area of a triable

# data[].attributes.body
Using line CB as the base, you have to find the altititude from vertice A to the base. Then when you find the length of the altitude and the base use the formula of are of triangles: bxh/2 and when you substitute and calculate, you get the area

# data[].attributes.body
Since it is area=bxhdivided by 2, u have to find the length of CB and the slope of CB, then do negative reprisal. Use formula to find area of triangle

# data[].attributes.body
First you measure the length of line CB and use the length formula. Then calculate the slope to create a negative reciprocal. Then use the formula for area to find the area of this triangle.

# data[].attributes.body
To find the area of the triangle you have to find the slope of CB and use point C or B to find the y intercept you can make an equation for CB. Then you take the slope of CB and do the negative reciprocal and then use point A to find the y intercept so you can make an equation. Then use the process of elimination to find the point of intersection between the 2 equations hen with that you use the POI with Point A and plug it in to the length formula to find the height. Then find area using formula

To find the area of the triangle you have

# data[].attributes.body
measure the length of CB using the length formula. then calculate the slope of CB. use the slope to make a negative reciprocal. then use bh/2 to find the area

# data[].attributes.body
we have to find the slope of CB which is the base. And then we have to use the slope to find the negative reciprocal which is the slope of the height (line that connects A to CB) use the slope to find the lengths of each line and use (b x h) / 2

# data[].attributes.body
Find the length of all the lines of the triangle, we also have to find the altitude. Then use the area formula to find the area

# data[].attributes.body
Use the length formula with the coordinates to find the length of each side. Then use the formula to find the area of a triangle (b x h)2
This will give you the area.
