The smallest angle is 1. It is acute and is smaller than a right angle. The largest angle is 2. It is obtuse and bigger than a right angle.
How do you know which angle is the largest?
Can you determine which angle is the largest? As you might guess, the largest angle will be opposite 18 because it is the longest side. Similarly, the smallest angle will be opposite the shortest side, 7. Therefore, the angle measure in the middle will be opposite 13.
What is a big angle called?
Angles larger than a right angle and smaller than a straight angle (between 90° and 180°) are called obtuse angles (“obtuse” meaning “blunt”). … Angles larger than a straight angle but less than 1 turn (between 180° and 360°) are called reflex angles.
Which side of XYZ is the longest?
Answer: XY is the longest side in the given ΔXYZ.
Which is the shortest side in right angle triangle?
In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.
What are the 7 types of angles?
The 7 types of angles are: right angles, acute angles, obtuse angles, straight angles, reflex angles, full angles, and complementary angles.
What are the 10 types of angles?
The different types of angles based on their measurements are: Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees.
…
Summary.
| Angle Type | Angle measure |
|---|---|
| Right angle | 90° |
| Obtuse angle | Greater than 90°, less than 180° |
| Straight angle | 180° |
| Reflex angle | Greater than 180°, less than 360° |
What are the 5 types of angles?
Different Types of Angles
- Zero Angles.
- Acute Angles.
- Right Angles.
- Obtuse Angles.
- Straight Angles.
- Reflex Angles.
- Complete Angle.
Which angle XYZ has the largest measure?
Angle X has the largest measure. There’s a rule that the largest angle is the one across from the largest side and since 5 is the largest side length and <X is across from it that’s your answer.
Which side of the triangle is the longest?
In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.
Which side of ABC is the longest?
Explanation: In any triangle, side opposite the largest angle is always the longest. and longest side of ΔABC is AB .
Is Side A always longer than Side B in a right triangle?
2 Answers. Side A and B does not matter when your trying to apply this to the pythagorean theorem but side C must always be the hypotenuse. The hypotenuse is always the triangle’s longest side. It is opposite the right angle.
Which is sin cos and tan?
Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos. this can be proved with some basic algebra.
What is a right angle triangle called?
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). … The side opposite the right angle is called the hypotenuse (side c in the figure).
