How do you find the smallest angle?
How do you find the smallest angle?
So, if given three side lengths, in order to put the angles in order from smallest to largest, first find the smallest angle by finding the angle opposite the smallest side, then, the medium-sized angle by finding the angle opposite the medium-sized side, and the largest angle opposite the largest side.
What is the largest angle?
The largest angle is 5 times the smallest angle, so the largest angle is 5x degrees….

| The third angle is 12 degrees more than the smallest angle. | Is 36 equal to 12 more than 24? Yes! |
How do you find the largest angle?
It is usually best to find the largest angle first, the one opposite the longest side. Then, set up a proportion using the Law of Sines to find the second angle. Finally, subtract these angle measures from 180° to find the third angle.
Is AAA a thing in geometry?
Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. Because there are 6 corresponding parts 3 angles and 3 sides, you don’t need to know all of them.
What does it mean if 2 angles are congruent?
Two angles are congruent if they have the same measure. Two circles are congruent if they have the same diameter.
What is SSS geometry?
When two triangles are congruent, all three pairs of corresponding sides are congruent and all three pairs of corresponding angles are congruent. If all three pairs of corresponding sides are congruent, the triangles are congruent. This congruence shortcut is known as side-side-side (SSS).
Is aas a congruence theorem?
Theorem 12.2: The AAS Theorem. If two angles and a nonincluded side of one triangle are congruent to two angles and a nonincluded side of a second triangle, then the triangles are congruent….Geometry.

Why is triangle 180 degrees?
A triangle’s angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.
Can a triangle have 2 90 degree angles?
Can a Triangle have Two Right Angles? Explain. No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°.
Can a right triangle have 2 obtuse angles?
Answer and Explanation: No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.
Why can a triangle only have one obtuse angle?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
Why can a triangle not have 2 obtuse angles?
When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle. The other two must each be less than 90 degrees (90 deg + 89 deg + 1 deg = 180 deg). It therefore follows that they must both be less than 90 degrees and so must both be acute.
