When your drawing an angle with a protractor after you've drawn the first side of the angle your next step is to do what?
say it is a 90 degree angle; find the 90 degree line on the protractor and draw a line continuing from it about 1/2 a centimetre. Remove the protractor and join up the lines
What does a 120 degree angle look like?
A 120-degree angle is an obtuse angle, which means it is greater than 90 degrees but less than 180 degrees. To visualize a 120-degree angle, imagine a clock face where the minute hand points to the 4 and the hour hand points to the 2. The angle between the hour and minute hands would be approximately 120 degrees.
Why cant you have two obtuse angles in a triangle?
Angle sum property of a triangle states that the sum of angles in any triangle should be 180 degree. An angle greater than 90 degree is an obtuse angle. If we have 2 obtuse angles in a triangle, say, 95 degree, 100 degree & 50, it always tend to violate the angle sum property of the triangle. So we cannot have 2 obtuse angles in a triangle.
What is a theta?
A theta is the latin word for a specific symbol used in mathematical equations. The theta means the angle. You use the theta symbol to say "angle". The symbol is useful when you don't know the degree of the angle is. * * * * * Theta is not Latin nor is it a word. It is a letter of the Greek alphabet. It is used to stand for an unknown angle in the same way that the Roman letters x or y are used in algebra.
What should you say when you meet an angle?
You're acute.
