What has 5 vertices 2 of which are right angles?
An irregular 5 sided pentagon can be constructed including two right angles.
How many face vertices and angle does a triangular prism have?
A triangular prism has 5 faces and 6 vertices. At each vertex it has three plane angles - making 18 two-dimensional angles.
What is the difference between 5 acute 2 obtuse and 5 right angles?
There are fewer obtuse angles than the other two kinds. There are the same number of acute and right angles and so the sum of the measures of the acute angles will be less than 5 right angles. The sum of two obtuse angles will be less than 5 right angles but may be less than, equal to, or more than 5 acute angles.
How many angles does a hexahedron have?
A hexahedron can have 5 to 8 vertices.
What is the name of a polygo with 4 right angles and has 5 sided?
It does not exist as a 5 sided polygon. To have 5 sides, it must have 5 angles (or vertices). The sum of the angles of a 5 sided polygon is (5-2) x 180o = 540o. The sum of 4 right angles is 4 x 90o = 360o → the 5th angle is 540o - 360o = 180o which is a straight line There are infinitely many points with such an angle along each of the sides; or to put it another way, for a vertex to exist it cannot have an angle of 180o. Thus if the polygon has 4 right angles, it cannot be a 5 sided polygon.
What shapes have 5 vertices and 2 right angles?
An irregular pentagon can have 5 vertices and two right-angles.
What has 5 vertices 2 of which are right angles?
An irregular 5 sided pentagon can be constructed including two right angles.
How many vertices does a stAR HAVE?
A star is not a specific shape: it is a generic word for a shape which has an even number of vertices. The interior angles at alternate vertices are usually reflex angles. A star can have six or more vertices.
How many face vertices and angle does a triangular prism have?
A triangular prism has 5 faces and 6 vertices. At each vertex it has three plane angles - making 18 two-dimensional angles.
How many right angles does a pentagonal prism have?
A pentagonal prism has 5 faces, with each face having 5 vertices. Each vertex connects two adjacent faces, forming a total of 10 right angles around each vertex. Therefore, a pentagonal prism has a total of 50 right angles.
What is the difference between 5 acute 2 obtuse and 5 right angles?
There are fewer obtuse angles than the other two kinds. There are the same number of acute and right angles and so the sum of the measures of the acute angles will be less than 5 right angles. The sum of two obtuse angles will be less than 5 right angles but may be less than, equal to, or more than 5 acute angles.
How many verticies does a square pyramid?
Well, a rectangular pyramid has four faces, (three triangles and a rectangle). So, this means that it will have only 5 vertices. The four that touch the base and the apex, or the one at the top:) So in total it has 5 vertices (corners)
How many angles does a hexahedron have?
A hexahedron can have 5 to 8 vertices.
What shape has 5 sides and two right angles and acute and obtuse angles?
It is an irregular pentagon.
What shape has two acute angles and two obtuse angles?
The shape could be a parallelogram (including a rhombus). Some kites would satisfy these requirements. And it is, of course, possible to have a shape with 5 or more vertices (i.e. more than 4 angles) that contains two acute and two obtuse angles.
What shape is formed using 5 congruent triangles and has 5 vertices 5 angles 5 sides?
pentagon
Does a pentagon have 5 right angles or 3?
Pentagons in normal (Euclidean) geometry can have at most three right angles, and the other two will be obtuse.However, in hyperbolic geometry, it is possible to construct a pentagon with 5 right angles, which is called a rectapentagon.
