Step-by-step explanation:
Area = 1/2[x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2)]
Now by putting all the values in the formula, we will get
Area of triangle = 1/2 [2(0 – (-4)) + (-1)((-4) – (3)) + 2(3 – 0)]
= 1/2 [8 + 7 + 6]
= 21/2
So, the area of triangle is 21/2 square units.
An acute angle is less than 90 degrees.
An obtuse angle is greater than 90 degrees.
A right angle is exactly 90 degrees.
A straight angle is exactly 180 degrees.
