Coordinate geometry is really useful when we need to work with angles and triangles! Here are a few ways it helps:
Plotting Points: When we place points on a grid, we can see how shapes and triangles are created. This makes it much easier to understand where the angles are located.
Finding Distances: We can use a simple formula to figure out how long the sides of a triangle are. The formula looks like this: ( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ). This helps us check if the triangle has the right properties.
Measuring Angles: With coordinate geometry, we can find slopes to see the angles between lines. The slope is calculated using this formula: ( m = \frac{y_2 - y_1}{x_2 - x_1} ).
Using coordinate geometry makes tough angle and triangle problems a lot easier to handle!
