47.5
It is an acute angle.
0
Yes. Angles are congruent if they have the same measure.
Those triangles with 25 and 90 degree angles are called right angle triangle.
Yes. It is so true that if they are side-by-side, you can hardly tell them apart.
A 25-degree angle is simply referred to as a "25-degree angle." In geometric terms, it's an acute angle since it measures less than 90 degrees. There isn't a specific name for this angle like there is for more commonly referenced angles such as 30 degrees or 45 degrees.
180-25=155 answer:155
A 90 Degree Angle
A 25 degree angle is an acute angle because it is greater than 0 but less than 90 degrees
Yes. They're so identical that you can't tell them apart. In fact, it sounds like you're talking about the same angle twice.
Use a protractor
Complementary angles add up to a right angle (90°). So 90° - 25° = 65° The way I remember the difference between complementary and supplementary is: think of a Straight line is 180° (Supplementary). Think of a Cross makes a 90° angle (Complementary)
