Theorems 4.1 Triangle Sum Theorem: The sum of the measures of the interior angles of a triangle is 180 o. Corollary: The acute angles of a right triangle are complementary. 4.2 Exterior Angle Theorem: The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent. Isosceles triangle theorem. If two sides of a triangle are equal in measure, then the angles opposite those sides are equal in measure.
Postulate 1: Two points determine a line. Postulate 2: Three noncollinear points determine a plane. The Pythagorean Theorem: The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. heorem: The sum of the angles in a triangle is 180°. Circle Theorems:
Chapter 1 Basic Geometry Example 1.6: The midpoint of segment AD $ $ $ $ is 1,2 ;. Point A has coordinates 3, F3 and point D has coordinates 𝑥,7 ;. It is helpful to use a line diagram when dealing with midpoint problems. Label the endpoints and midpoint, and identify the coordinates of each:
Postulate 1: To draw a straight line from any point to any point. Postulate 2: To produce a nite straight line continuously in a straight line. Postulate 3: To describe a circle with any center and distance. Postulate 4: That all right angles are equal to one another.
Postulate 1-4 – Through any three noncollinear points there is exactly one plane. Acute Angle: an angle whose measure is less than 90 and greater than zero. n angle whose measure is greater than 90 an. Right Angle: an angle whose measure is 90. . Congruent Angles – ∠ ≅ ∠ ∠. iff ∠ =
Introduction to proofs: Identifying geometry theorems and postulates C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? 2) Why is an altitude? 3) Why are the triangles congruent? 4) Why is NM a median? 5) If ABCD is a parallelogram, why are LA and 6) Why are the triangles congruent?
