**Coordinate Geometry Proofs Answer Key**

### Why use variables as coordinates when writing a safe coordinate?

A coordinate arc means that the geometric shapes are placed on a coordinate plane. When you use variables to display the coordinates of a shape in a coordinate box, the results apply to all shapes of that type. Place each figure on a coordinating plane so that it helps you determine the lengths of the sides.

### The question is also what is a safe coordinate?

Coordinate the rehearsals. The certainty of the coordinates is the proof of a geometric theorem that uses to argue generalized points on the Cartesian plane. The method typically involves assigning variables to the coordinates of one or more points and then using those variables in the center point or distance formulas.

### Besides the above, how can one prove that a triangle is isosceles using coordinates?

The simplest way to use coordinate geometry to prove a triangle is isosceles is to use its sides. Coordination of the testing process

- Draw the 3 points (optional)
- Use the distance formula to calculate the length of the sides on each side of the triangle.
- If 2 sides have the same length, the triangle is isosceles.

Similarly, one might ask, what is an example of coordinated evidence?In a coordinate vault, you prove geometric statements with algebra and the coordinate plane. Here are some examples of statements that you can prove with a coordinate proof: Prove or deny that the square defined by the points, e.g. {Align *} (2.4), (1,2), (5.1), (4.1) so {align *} is a parallelogram.

### What proofs are numbers used for?

A proof that uses shapes on a coordinate plane to prove geometric properties is called trigonometric.

### How do you find a slope?

The slope of a line characterizes the direction of a line. To find the slope, divide the difference between the y coordinates of 2 points on a line by the difference between the x coordinates of the same 2 points.

### How is it shown with the help of coordinate geometry that the diagonals of a parallelogram intersect at their center?

To prove that the diagonals intersect in their center, we must show that they have the same center, that is, we must show that their centers have the same coordinates. Since the centers of the diagonals have the same coordinates, the theorem is proved.

### How is a square shown?

Geometry for Dummies, 2nd edition If a square has four congruent sides and four right angles, it is a square (inverted from the definition of a square). If two consecutive sides of a rectangle are congruent, it is a square (neither the inverse of the definition nor the inverse of a property).

### How do you show a rectangle in coordinate geometry?

The diagonals are congruent. Let's see why we can say that the diagonals are congruent. Here is an example of evidence: Data: the ABCD square is a rectangle. Show that it is a rectangle. Explanations Causes AD BC Definition of rectangle DC DC Reflective property
