# What is the meaning of sarcastic?

## What is the meaning of sarcastic?

## What is obtuse Behaviour?

The adjective **obtuse** is good for describing someone slow on the uptake: "Don't be so **obtuse**: get with the program!" The adjective **obtuse** literally means "rounded" or "blunt," but when it's used for a person, it means "not quick or alert in perception" — in other words, not the sharpest tool in the shed.

## What does a obtuse triangle look like?

An **obtuse**-angled **triangle** is a **triangle** in which one of the interior angles measures more than 90° degrees. In an **obtuse triangle**, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the **triangle** ABC is an **obtuse triangle**, as ∠A measures more than 90 degrees.

## What are the sides of an acute triangle?

Properties of Acute Triangles An **equilateral triangle** has three sides of equal length and three equal angles of 60°. An acute triangle has three inscribed **squares**. Each **square** coincides with a part of a triangle side. The other two vertices of a **square** are on the two remaining sides of the acute triangle.

## How do you classify a triangle by its side lengths?

**Classifying Triangles** by **Sides**

- scalene
**triangle**-a**triangle**with no congruent**sides**. - isosceles
**triangle**-a**triangle**with at least 2 congruent**sides**(i.e. 2 or 3 congruent**sides**) - equilateral
**triangle**-a**triangle**with exactly 3 congruent**sides**. - NOTE: Congruent
**sides**means that the**sides**have the same**length**or measure.

## What are the rules of a right triangle?

The Pythagorean **theorem** states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

## What are the side lengths of a 30 60 90?

A **30**-**60**-**90** triangle is a special right triangle whose angles are 30º, 60º, and 90º. The triangle is special because its **side lengths** are always in the ratio of 1: √3:2. Any triangle of the form **30**-**60**-**90** can be solved without applying long-step methods such as the Pythagorean Theorem and trigonometric functions.

## What are the possible side lengths of a triangle?

SOLUTION: The sum of the **lengths** of any two **sides** of a **triangle** must be greater than the **length** of the third **side**. Since, 6 + 14 > 10, 6 + 10 > 14, and 10 + 14 > 6, you can form a **triangle** with **side lengths** 6 m, 14 m, 10 m.

## What is the rule for the third side of a triangle?

Triangle Inequality **Theorem**. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

## How do you find the third side of a triangle if two sides are known?

Just like the Law of Sines, the Law of Cosines works for any **triangle**, not just right **triangles**. In particular, the Law of Cosines can be used to find the length of the **third side of a triangle when** you know the length of **two sides** and the angle in between.

## How do you find the length of the third side of a triangle?

**The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.**

- So, difference of two
**sides**
