Angles are undefined terms in plane geometry.
The true statements are:
- <em>4. </em><em>.</em>
- <em>5. </em><em />
- <em>6. </em><em> is an obtuse angle</em>
- <em>7. Its supplement must be an acute angle</em>
- <em>8. See attachment</em>

<u>Question 4</u>
The first statement is represented as:
Supplement of
means that A and B are congruent.
The supplementary of A and B would be the same
The measure of A is then calculated as:
Subtract 22 from both sides
<u>Question 5</u>
If LP and LQ are linear pairs, then:
So:
Substitute
Subtract 90 from both sides
<u>Question 6</u>
--- S and T are supplementary
--- T and U are complementary
Subtract both equations
Make U the subject
This means that:
Hence, is an obtuse angle
<u>Question 7</u>
Obtuse angles are greater than 90 degrees but less than 180.
This means that their supplement must be an acute angle (i.e. less than 90)
<u>Question 8</u>

The Answer to the question is 1.
Answer is 2/8 or 1/4
Explanation: 1 is the number for all of the students, 6/8 is the students not wearing blue shirts, so 1- 6/8 equals 2/8 which can be simplified to 1/4.
