Warm-up Write the following formulas 1.Distance 2.Midpoint What is the Pythagorean Theorem?
Ch. 4.7 Coordinate Geometry Students will place geometric figures in a coordinate plane and write a coordinate proof.
Example 1: A right triangle has legs of 6 and 8 units. Place the triangle in a coordinate plane. Label the coordinates of the vertices and find the length of the hypotenuse.
Cool Down A right isosceles triangle has legs measuring n units. Find the length of the hypotenuse.

EXAMPLE 4 Apply variable coordinates
Lesson 4-7 Triangles and Coordinate Proof
The Pythagorean Theorem. The Right Triangle A right triangle is a triangle that contains one right angle. A right angle is 90 o Right Angle.
Proofs Using Coordinate Geometry
The Pythagorean Theorem x z y. For this proof we must draw ANY right Triangle: Label the Legs “a” and “b” and the hypotenuse “c” a b c.

Geometry 1-6 Midpoint and Distance. Vocabulary Coordinate Plane- a plane divided into four regions by a horizontal line (x-axis) and a vertical line (y-axis).
Midpoint and Distance Formulas Goal 1 Find the Midpoint of a Segment Goal 2 Find the Distance Between Two Points on a Coordinate Plane 12.6.
8-1, 1-8 Pythagorean Theorem, Distance Formula, Midpoint Formula
Congruent Segments – › Line segments that have the same length. Midpoint – › The point that divides a segment into two congruent segments. Segment.
The Distance and Midpoint Formulas
Section 11.6 Pythagorean Theorem. Pythagorean Theorem: In any right triangle, the square of the length of the hypotenuse equals the sum of the squares.
