How many different isosceles triangles have at least one angle that measures exactly 20?
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.
If two angles are supplementary and one angle measures 130 degrees what is the measure of the other angle?
Supplementary angles add up to 180 degrees. If one angle = 130 degrees the other must be 180 - 130 = 50 degrees
How do you calculate perimeter of irregular figures?
The exact method varies according to the figure. You must somehow calculateor measure the length of each segment of the outline, and then sum them.
Two angles are supplementary and one measures 60 less than the other Find the measure of the larger angle?
Two supplementary angles add up to 180 degrees. If one measures 60 less than the other, they must be 60 and 120 degrees, so the measure of the larger angle is 120 degrees. To find that algebraically, where m is the larger angle: m+(m-60)=180 2m=240 m=120
What must be true if a segment intersects another segment at more than one point?
That means that it is not a line segment.
What are the five measures to be taken during designing your garden?
When designing a garden one must take five measures of action. The first of these measures is to measure the area.
How many different isosceles triangles have at least one angle that measures exactly 20?
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.

If the sum of the measures of two angles of a triangle is equal to the measure of the third angle the triangle must be?

If each side of a regular polygon has a measure of 156 then the polygon must have how many sides?
If each interior angle measures 156 degrees then it must have 15 sides
If two angles are supplementary and one angle measures 130 degrees what is the measure of the other angle?
Supplementary angles add up to 180 degrees. If one angle = 130 degrees the other must be 180 - 130 = 50 degrees
What is the measure of an angle complement?
The complement of an angle which measures D degrees, where D must be less than 90, is 90 - D.
If a point is equidistant from the endpoints of a segment, then it must be the midpoint of the segment?
Yes
What is the measure of the forth angle of a quadrilateral if one angle measures 106 degrees and the other measures 47degrees and the third one measures 133?
The sum of the interior angles of a quadrilateral must equal 360 degrees. If you know three of the angles, just subtract them from 360 to find the fourth angle. In this case: 360 - 106 - 47 - 133 = 74
All of the measures in a song contains four beats One of the measures contains a half note a quarter note an eighth note and one other note must be?
The final note in the measure would be a second eighth note. This would ensure the notes added up to four beats.
