1. An angle that is between 0° and 90° is an ACUTE ANGLE.
2. Angles, segments, triangles, etc that have exactly the same measures are CONGRUENT.
3. Two angles that add up to 180° are SUPPLEMENTARY ANGLES.
4. Angles that are opposite to one another at the intersection of two lines are VERTICAL ANGLES.
5. Two angles in a common plane which share a common Bertrand a common side but do not overlap are ADJACENT ANGLES.
6. Two angles that add up to 180° that share a common vertex are ADJACENT SUPPLEMENTARY ANGLES.
7. Two angles that are located between two coplanar lines on opposite sides of the transversal are ALTERNATE INTERIOR ANGLES.
8. Two angles that are located outside two coplanar lines on opposite sides of the transversal are ALTERNATE EXTERIOR ANGLES.
9. Two angles that are located between two coplanar lines on the same side of the transversal are CONSECUTIVE INTERIOR ANGLES.
10. Two angles that are formed by two coplanar lines and a transversal and occupy the same relative positions are CORRESPONDING ANGLES.
11. An angle that is 180° is a STRAIGHT ANGLE.
The March sales of Jazz records is an illustration of proportions, and the number of jazz records sold all year is 7x
<h3>How to determine the total number of sales?</h3>
The sales in March is given as:
Proportion = 1/7
Let the actual number of sales in the month of March be x, and the total sales in the year be y.
So, we have:
1/7 * y = x
Make y the subject
y =7x
Hence, the number of jazz records sold all year is 7x

The Greatest Common factor(GCF) of -2x^2-4x-6 is -2(x+1)(x-3)
<h3>What is Greatest Common Factor?</h3>
The greatest common factor (GCF) is the largest factor two or more numbers have in common
From the question,
-2x^2-4x-6
By collecting like terms
-2(x^2-2x-3)
By factoring x^2-2x-3
-2(x^2-3x+1x-3)
Collecting like terms
-2(x^2-3x)+(x-3)
-2(x(x-3)+1(x-3))
-2(x+1)(x-3)
hence -2(x+1)(x-3) is the Greatest Common factor of -2x^2-4x-6 is
