# How are all of the right angles similar?

90 degrees. AMERICA!

### Are all right angles similar?

All right angles measure 90 degrees, that is, one-quarter of a full circle. If the angle doesn't measure 90 degrees it isn't a right angle; all right angles are identical.

### How can you tell whether two polygons are similar?

Polygons will be similar if they have the same number of sides AND all of their angles are the same. All of their angles are the same if all but one of their angles are the same because with the same number of sides the angles must add up to the same thing. All squares are similar (4 right angles and sides of equal lenght). All rectangles are similar (4 right angles). We know two… Read More

### All angles are right angles but all sides are not equal?

You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.

yes there similar

### Are two right triangles congruent why or why not?

Not necessarily. Even if all three angles of one triangle are the same as the corresponding angles of the other, the triangles may be similar but not congruent. And in this case, you don't even know that all three angles are the same.

### Do all right angles measure 90 degrees?

Yes. All 90-degree angles are "right angles", and all right angles are 90 degrees. Anything else is not a right angle.

### How are the quadrilateral square and rhombus similar?

A square is a rhombus - it has all the properties of a rhombus. A square also has the additional property that all angles are right angles. This means that all squares are rhombuses, but not all rhombuses are squares. squares are quadrilaterals.

### Can a parallelogram have 5 right angles?

### Can right triangle and acute triangles be similar?

No because a right ange triangle has a 90 degree angle and 2 acute angles whereas an acute triangle has 3 acute angles all of which are less than 90 degrees

### What are similarities of congruent shapes and similar shapes?

The angles for congruent shapes and the angles in similar shapes are all the same. All the sides are also proportional in both. Basically, all congruent shapes are similar but not all similar shapes are congruent.

### Rectangular prism all angles are acute angles?

rectangular prism all angles are acute angles yes or no? * * * * * No, none of the angles are acute. They are all right angles because each face is a rectangle and each angle in a rectangle is a right angle.

### All of the angles of a quadrilateral are congruentcan the quadrilateral be a pallegram?

### Has four right angles and all its equal?

A square has four right angles and all sides are equal.

### What is a quadrilateral with all four right angles?

A rectangle has four right angles. A square also has 4 right angles, but it is a only a square and not a rectangle if all of the sides are congruent.

### How many right angles on all the faces of a rectangular prism?

A rectangular prism has six faces; each face has four right angles. There are 24 right angles in all.

### What rectangles are similar to a 10 by 15?

All rectangles which have sides in the ratio 10:15 would be similar. This would include 2 x 3, 4 x 6, 100 x 150, etc. Note that similarity in rectangles is very simple, since all interior angles are by definition right angles.

### Pentagon with 3 right angles?

A pentagon with 3 right angles is considered to be an irregular pentagon because not all angles and all sides are equal.

### How are perpendicular lines similar to intersecting lines?

Intersecting lines meeting at right angles are perpendicular lines. Intersecting lines meeting at right angles are perpendicular lines.

### All right angles are what?

Right angles are ninety degree angles. That is equal to one quarter of a complete rotation.

### Does a parallelgram have all right angles?

It depends. Most parallelograms don't have all right angles. However, there is a special type of parallelogram that has all right angles. You probably know this shape by its proper name, a rectangle.

### What is similar about all triangles?

they all have three sides, three angles, and the sum of their angles is always 180 degrees.

### How numbers got their shape?

The Arabic numbers, which is what are numbers are based on for the English language and are very similar to, use to have no curves or curved angles in them and had all acute, obtuse, or right angles. According to what number it was (for example 3) had three angles. Another example is 4, which still has four angles today.

### Does a rectanglehave at least two angles less or two angles greater than a right angle?

All of the angles in a rectangle are right angles.

### How many right angles altogether are there in all faces of a cube?

there are 24 right angles in all faces of a cube

### Can all triangles have right angles?

yes they can,they can have right angles because if you turn it then you would have a right angle

### What kind of angles are always congruent?

All right angles are congruent, and all straight angles are congruent.

### It has 4 sides all of its angles and all angles are right angles and its 4 sides are not all the same length?

Quadrilateral

### What quadrilateral has all angles congruent?

The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.

### Do some rectangles have no right angle?

### How do you tell if a square has right angles without measuring?

all squares have right angles

### Does all Quadrilaterals have at least one right angles?

No, a quadrilateral does not necessarily have any right angles. If it has a right angle, it will necessarily have four right angles, and will be a rectangle. But not all quadrilaterals are rectangles. As long as a polygon has four sides, it is a quadrilateral. It might have, for example, two angles of 100o and two angles of 80o.

### Can a rectangle be a square explain?

a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.

### What shape has three sides and all right angles?

The following shape has three sides and the only angles are right angles. ----- | |___

### Triangle in which all of the angles are acute angles?

They are possible - unlike plane triangles in which all of the angles are right angles, obtuse or larger.

### Why can't two acute angles solve a right triangle?

Because another triangle could have exactly the same angles, but its sides could all be twice as long, or 62 times as long etc. There are an infinite number of triangles that all have the same two acute angles. They're all similar to each other, but they're not congruent.
