A rhombus is a four sided polygon which like all other four sided shapes are known as quadrilaterals. What they all have in common is that the total sum of their interior angles add up to 360 degrees.
A twenty-sided polygon is called an "icosagon" If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the centre from each angle.. There will be 20 small angles arranged in a circle around the centre. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.
Because the 4 interior angles of any quadrilateral add up to 360 degrees and a cyclic quadrilateral diagonals opposite angles add up to 180 degrees therefore it follows that the other pair must be 180 degrees
Opposite angles are equal, so:One of the angles can be anything between 0 and 180 degrees (exclusive). Call this "x".The opposite angle must be the same - also "x".The other two angles must be 180 - x.
It is a square, a regular parallelogram with all right angles. The reason is that in a parallelogram, the adjacent angles are supplementary (equal 180 degrees).In any case, the opposite angle would be 90 degrees as well, leaving just 180 degrees for the other two identical opposite angles.
The same again 50 and 130 degrees because a rhombus is a quadrilateral and all quadrilaterals have a total of 360 interior degrees.
It has 4 interior angles that add up to 360 degrees and 2 diagonals that intersect each other at right angles.
A rhombus is a four sided polygon which like all other four sided shapes are known as quadrilaterals. What they all have in common is that the total sum of their interior angles add up to 360 degrees.
If the rhombus has two angles of 112 degrees - then the other two angles must total 136 degrees.
A rhombus is a four sided quadrilateral whose total sum of interior angles amount to 360 degrees. Opposite angles are equal in a rhombus. Therefore: 35 degrees+35 degrees = 70 degrees. 360 degrees - 70 degrees = 290 degrees which then is split in two to give you the other two angles: 290/2 = 145 degrees. So the answer to your question is A 35 degrees 145 degrees 145 degrees.
140, 40 and 140. Since the adjacent angles of a rhombus are supplementary angles and one of them is 40 degrees, the other is (180 - 40)140 degrees. So that two others are 40 and 140 degrees, as congruent opposite angles of the rhombus.
The other 3 angles are 27.5 degrees, 152.5 degrees and 152.5 degrees because opposite angles are equal in a parallelogram and its 4 interior angles add up to 360 degrees.
First of all, a square is a special kind of rhombus, so you would naturally expect it to have all of the properties of any other rhombus, plus a few special ones of its own. -- four sides of equal length -- two sets of parallel sides -- four interior angles that sum to 360 degrees -- four exterior angles that sum to 360 degrees -- opposite angles equal -- adjacent angles supplementary
They are both quadrilaterals with 4 equal sides They both have 2 diagonals that bisect each other at 90 degrees They both have 4 exterior and 4 interior angles that add up to 360 degrees respectively A square has 4 right angles but a rhombus has 2 equal opposite obtuse angles and 2 equal opposite acute angles A rhombus looks like a tilted square
360 degrees. Same for any other rectangle, rhombus, parallelogram, or convex quadrilateral. The reason is that any quadrilateral can be divided into two triangles by drawing a diagonal and the sum of the angles of each triangle is 180 degrees.
The diagonals of a rhombus are perpendicular which means that they intersect each other at right angles or at 90 degrees.
The diagonals of a rhombus are perpendicular and intersect each other at right angles which is 90 degrees
