Square: A quadrilateral with four congruent sides and 4 right angles a square is both a rhombus along with a rectangle. Trapezoid: A quadrilateral with exactly one set of parallel sides (the parallel sides are known as bases) Isosceles
Isosceles triangle
In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
Which quadrilateral always has four congruent angles?
There are two types of quadrilateral that always have four congruent sides: square and rhombus. Likewise, what type of quadrilateral has 4 congruent sides and 2 obtuse angles? rhombus
How many sides and angles does a quadrilateral have?
The four angles in a quadrilateral always add up to 360°. This rule is true for all quadrilaterals. A quadrilateral is any 4-sided shape. Quadrilaterals also always have 4 angles. For example, the 4 angles in a rectangle are all 90°.
Is it possible to have quadrilateral with four obtuse angles?
No. Since the sum of the 4 angles of a quadrilateral is 360° , if three angles are obtuse, ie greater than 90°, it is not possible for the 4th angle to also be greater than 90° also. If it were the sum of the 4 angle would be greater than 360° and that s not possible for a quadralateral. 176 views. ·.
What is the sum of the angles in a quadrilateral?
The angles of a quadrilateral are the angles formed inside the closed shape. The sum of interior angles of a quadrilateral is 360 degrees. Let’s prove that sum of all interior angles of a quadrilateral is 360 degrees. Each quadrilateral has 4 angles. The sum of its interior angles is always 360 degrees.

What are the different types of quadrilaterals?
Types of Quadrilaterals. There are special types of quadrilateral: Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See below for more details.
How many sides does a quadrilateral have?
It has two pairs of sides: Each pair is made of two equal-length sides that join up. Also: the angles where the two pairs meet are equal. the diagonals, shown as dashed lines above, meet at a right angle. one of the diagonals bisects (cuts equally in half) the other. ... and that's it for the special quadrilaterals.
What is a parallelogram?
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
What is a rectangle?
A rectangle is a four-sided shape where every angle is a right angle (90°).
Is a quadrilateral a square?
The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.
Where do diagonals meet?
Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
Which trapezoid has left and right sides of equal length that join to the base at equal angles?
An Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.

What is a quadrilateral with only 2 right angles?
Explanation: Given: A quadrilateral with only 2 right angles. A parallelogram is a quadrilateral with 2 pair of opposite sides parallel. A rectangle is a special parallelogram that has 4 right angles. A square is a special rectangle that has all four sides congruent. A kite has two consecutive sides congruent.
How many sides does a kite have?
A kite has two consecutive sides congruent. The angle between these two sides could be a right angle, but there would only be one right angle in the kite. A trapezoid is only required to have two parallel sides. However, a trapezoid could have one of the sides connecting the two parallel sides perpendicular to the parallel sides which would yield ...
Can a trapezoid have two right angles?
However, a trapezoid could have one of the sides connecting the two parallel sides perpendicular to the parallel sides which would yield two right angles. Answer link. Alan P. May 19, 2018.
