Obtuse Triangle | An obtuse triangle is a triangle with one angle that is greater than 90 degrees. |

Right Triangle | A right triangle is a triangle with one 90 degree angle. |

Triangle | A triangle is a polygon with three sides and three angles. |

What angle measures 60?

Constructing a **60**° **angle** This construction works by creating an equilateral triangle. Recall that an equilateral triangle has all three interior **angles 60**°. We use one of those **angles** to get the desired **60 degree** result.

###
How do you find the measure of an angle?

Using a Protractor The best way to **measure** an **angle** is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the **angle’s measurement** to the nearest degree.

###
What is a unique triangle?

The two angles and any side condition determines a **unique triangle**. Since the condition has two different arrangements, we separate it into two conditions: the two angles and included side condition and the two angles and the side opposite a given angle condition.

###
How much degrees is an equilateral triangle?

You’ll notice that along with this **triangle’s** sides, its three angles are also all equal. Since the sum of a **triangle’s** angles is always 180 **degrees**, each angle in an **equilateral triangle** must measure 60 **degrees**.

###
How many degrees is a triangle?

180

###
How many degrees is an scalene triangle?

180 degrees

###
How do you find the angle of a triangle given two sides?

**Examples**

- Step 1 The two sides we know are Opposite (300) and Adjacent (400).
- Step 2 SOHCAHTOA tells us we must use Tangent.
- Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
- Step 4 Find the angle from your calculator using tan-1

###
How many degrees is a line?

The angles on a straight **line** add up to 180 **degrees**.

###
Can a triangle have two obtuse angles?

**Two obtuse angles** by definition mean that there would be **two angles** of (at least) 91 degrees each. Therefore, a **triangle can** never **have** more than one **obtuse angle**. When an **angle** of a **triangle** is 90 degrees, the **triangle** cannot **have** an **obtuse angle**.

###
How many degrees is a square?

All four angles of a **square** are equal. (Each is 360°/4 = 90°, so every angle of a **square** is a right angle.) All four sides of a **square** are equal.

###
How many degrees is a quadrilateral?

360 degrees

###
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).

###
Can a triangle have two right angles?

Answer Expert Verified In Euclidian (flat) geometry the sum of all **angles**, in a **triangle**, by definition, must be equal to 180 degrees. So, we **can**‘t **have two right angles** in a **triangle**, only one, because the sum of **two** other **angles** must be 90 degrees.

###
How do you identify a triangle type?

- Acute Triangle: All angles are less than 90°.
- Obtuse Triangle: One angle is greater than 90°.
- Right Triangle: One angle is 90°.
- Equilateral Triangle: 3 equal sides. 3 equal angles.
- Isosceles Triangle: 2 equal sides. 2 equal angles.
- Scalene Triangle: No equal sides. No equal angles.

###
Is a triangle a polygon?

As you learned in the last lesson, a **triangle** is the simplest **polygon**, having three sides and three angles. The sum of the three angles of a **triangle** is equal to 180 degrees. **Triangles** are classified by sides and by angles. Move your cursor over the **triangles** to learn more.

###
What does obtuse triangle mean?

An **obtuse triangle** (or **obtuse**-angled **triangle**) **is** a **triangle** with one **obtuse angle** (greater than 90°) and two acute angles.

###
What triangle Cannot be drawn?

Triangle Inequality **Theorem** One According to the first triangle inequality **theorem**, the lengths of any two **sides** of a triangle must add up to more than the length of the third **side**. This means that you cannot draw a triangle that has **side** lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.

###
What type of angles are in a triangle?

The right **triangle** has one 90 degree **angle** and two acute (< 90 degree) **angles**. Since the sum of the **angles** of a **triangle** is always 180 degrees The two sides of the **triangle** that are by the right **angle** are called the legs and the side opposite of the right **angle** is called the hypotenuse.
