Tomorrows quiz will include questions very similar to the following...
A circle has a radius of 4 cm, find the diameter, circumference, and area
Answers:
radius = 4cm
diameter = 8cm
Circumference = 25.12 cm
Area = 50.24 square cm
A triangle has angles of 90, 30, and "x". What is the value of x?
Answer: 60 degrees (every triangle has a total of 180 degrees)
What angle is supplementary to an angle of 60 degrees?
Answer: 120 degrees (supplementary angles have a sum of 180 degrees)
What angle is complementary to an angle of 30 degrees?
Answer: 60 degrees (supplementary angles have a sum of 90 degrees)
There will be a question that requires finding the perimeter and area of an irregular polygon (we did a worksheet on this in class today)
If students feel comfortable with the homework assignment from today, they will have no problem with the quiz tomorrow. We will take the first 15-20 minutes of class to go over the homework assignment before taking the quiz.
Here are the solutions to todays homework
1.) r = 6cm d = 12cm C = 37.68cm A = 113.04 sq cm
2.) r = 9m d = 19m C = 59.66m A = 254.34 sq cm
3.) 50 degrees (supplementary angles)
4.) 50 degrees (sum of a triangle is 180 degrees)
5.) 60 degrees (sum of a triangle is 180 degrees)
6.) Segment EF (parallel lines)
7.) Segment EA or FD (perpendicular lines)
8.) right triangle or scalene triangle
9.) P = 40 cm A = 60 sq cm
10.) P = 34 m A = 36 sq m
