What set of numbers is the acute and which is the obtuse numbers on a protractor?
ArchuloverCrush
A right angle sits at 90o, which is right in the middle. Anything less than 90o, or to the left on the protractor are acute angles. Anything to the right, or bigger than 90o, would be considered an obtuse angle. A good way to remember this is that an acute angle is "a cute little angle."

How do you know which set of numbers on a protractor you are suppose to use when measuring angles on a circle graph?
Assuming you've got a 180o protractor (and not a 360o angle measurer).To measure an acute, right or obtuse angle (ie 0o to 180o):Place the centre mark of the protractor on the centre of the angle (ie where the arms of the angle meet)Put one of the base lines (which will be marked 0o and 180o) on one of the arms of the angle, so that the other line of the angle is within the scale of the protractor.Use the scale which starts with 0o on the first arm to read off the angle to the other arm.To measure a reflex angle (ie 180o to 360o):Place the protractor centre as abovePut the base line as aboveUse the scale which starts with 180o on the first arm to read off the angle to the other arm.Add 180o to the angle found in step 3.
What shape has 1 set of parallel sides 2 sets of perpendicular sides?
It could be a trapezoid having 2 right angles, an obtuse angle and an acute angle
What tool is used to draw a right angle?
A protractor is used to draw a right angle of 90 degrees.
What are instruments used in geometry?
Scale, protractor,compass,divider,set square
How do to measure an angle?
To measure angels you use a so called Protractor. Practice lining up and reading a protractor while you measure a set of angles in this fun learning activity. The angles may range from 0° to 180°. The interactive protractor is already lined up with the vertex of each angle but you will have to rotate the protractor into proper position. The margin of error is only 1° and you must report measurement to the nearest whole number.
What kind of angle does a rhombus have?
Two acute angles and two obtuse angles. If you do not know what these angles are, I will show you. An acute angle is an angle that has less than 90 degrees on your protractor (Shaped like a semi-circle. Found in a mathematical set). An obtuse angle has more than ninety degrees. An angle with ninety degrees is a right angle.
Why does a protractor have 2 sets of numbers on it?
You measure angles from either side of the protractor. One set of numbers measures from the left side, the other measures from the right side.
What shape has a set of parallel lines and two obtuse angles and 2 acute angles?
It's you dumbo!no its not
Why does a protractor have two sets of numbers?
Because on set measure from the right and the other measures from the left
Which set of numbers represent the side lengths of an obtuse triangle?
Those ones, there!
What shape has 1 right angle 2 acute angles and 1 obtuse angle with 4 side and 1 set of parallel lines?
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
What is a six-letter word for a line with angles that is not straight?
Obtuse Yes, For a line set that has an angle greater than 90 degrees, the line set is "OBTUSE". For a line set that has an angle less than 90 degrees, the line set is "ACUTE". For a line set that has an angle equal to 90 degrees, the line set is "RIGHT ANGLE".
What shape has two right angles only one set of parallel sides and no lines of symmetry?
It is a trapezoid and its other 2 angles are obtuse and acute

What is a figure that only has one set of parallel lines no perpendicular lines and at least one acute angle and the one obtuse angle?
A polygon with four or more sides can meet all of the requirements.
What tool is used to draw a right angle?
A protractor is used to draw a right angle of 90 degrees.
