Chapter 1.1 • Colinear • Coplanar • Intersection of two planes or lines • How to name a line, plane, point, etc.
Chapter 1.2 D is the midpoint of EF, ED = 4x + 6, and DF = 7x – 9. Find ED, DF, and EF. Measuring Distance Between, Midpoint, Bisector Segment and Addition Postulate Problems like:
Chapter 1.3 KM bisects JKL, mJKM= (4x + 6)°, and mMKL= (7x – 12)°. Find mJKM.
mWYZ= (2x – 5)° and mXYW= (3x + 10)°. Find the value of x.
Chapter 1.4 Complementary and Supplementary If XYZ and PQR are supplementary, find the measure of each angle. mXYZ= 2x° and mPQR= (8x - 20)°. Vertical Pair
Chapter 1.5 Formulas and solving for missing variables: • Square, Triangle, Rectangle • Circle • Chapter 1.6 • Midpoint • Distance • Pythagorean Theorem
Area of a square = 40 sq cm, what is side measure? • Area of a Circle = 36 sq cm, find the diameter. • Perimeter of a rectangle = 80, base = 6, find height. • Triangle area = 25, base = 5, find height. • Circumference of a circle is 80, what is area?
