## What is the difference between digress and regress?

Digress means to side track or to divert attention from the topic at hand: “Her speech often seemed to digress from the main topic of the seminar.” Regress is to move backward, either physically or in one’s thinking: “In old age, one’s body regresses.”

## What is the opposite of 14?

## How do you do special right triangles?

Step 1: This is a right triangle with two equal sides so it must be a 45°-45°-90° triangle. Step 2: You are given that the both the sides are 3. If the first and second value of the ratio x:x:x√2 is 3 then the length of the third side is 3√2. Answer: The length of the hypotenuse is 3√2 inches.

## What do scalene triangles have?

A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

## What are the ratios of a 30 60 90 Triangle?

A 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 /b> can be solved without applying long-step methods such as the Pythagorean Theorem and trigonometric functions.

## What’s the opposite of 60 degrees?

The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle. And, finally, the side opposite the 90° angle will always be the largest side (the hypotenuse) because 90 degrees is the largest angle.

## What type of triangle is 60 60 60?

This is a triangle (that is, an equilateral triangle), with sides having a length of two units.

## What is the type of triangle?

There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. A triangle’s name also depends on the size of its inside angles: acute if all angles are less than 90°, right-angled if one angle is 90°, or obtuse if one angle is more than 90°.

## How do you solve a 15 75 90 Triangle?

All that remains to know the length ratios for the sides of the triangle is to determine the length of EC, its hypotenuse, via the Pythagorean Theorem. The square of length EC must equal the square of 1 plus the square of (2 – √3), so EC, squared, equals 1 + 4 – 4√3 + 3, or 8 – 4√3.

## What are the sides of a 90 degree triangle?

A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.

## What are the lengths of a 45 45 90 Triangle?

A 45°-45°-90° triangle is a special right triangle that has two 45-degree angles and one 90-degree angle. The side lengths of this triangle are in the ratio of; Side 1: Side 2: Hypotenuse = n: n: n√2 = 1:1: √2. The 45°-45°-90° right triangle is half of a square.

## What part of speech is digress?

digress

part of speech: intransitive verb
inflections: digresses, digressing, digressed

## Can 30-60-90 angles make a triangle?

A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.

## What are the special triangles in trigonometry?

THERE ARE TWO special triangles in trigonometry. One is the 30°-60°-90° triangle. The other is the isosceles right triangle. They are special because, with simple geometry, we can know the ratios of their sides.

## Are all isosceles triangles 30-60-90?

This is an isosceles right triangle. The other triangle is named a 30-60-90 triangle, where the angles in the triangle are 30 degrees, 60 degrees, and 90 degrees….45-45-90 and 30-60-90 Triangles.

Hypotenuse Length Leg Length

## What is a scalene and right?

Isosceles: means “equal legs”, and we have two legs, right? Also iSOSceles has two equal “Sides” joined by an “Odd” side. Scalene: means “uneven” or “odd”, so no equal sides.

## Which triangle is both scalene and right?

An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. A right triangle has one right angle.

## Why is it called a scalene triangle?

The term scalene triangle is derived from Late Latin ‘scalēnus’ and from the Ancient Greek word ‘σκᾰληνός’ which means unequal or uneven.
