No, a triangle and a rectangle are not congruent. Congruent means exactly the same size and shape. A triangle has 3 sides while a rectangle has four. A triangle's three angles always add up to 180 degrees where as a rectangle's four right angles always equal 360 degrees. They are not congruent- not even similar- at all.
A quadrilateral with two sets of parallel side and right angles is called a rectangle. If all the sides are the same size it is also called a square.
They are both two dimensional. They only have right angles at line intersections. Opposing sides are parallel. Opposing sides are the same size.
Yes. Similar figures are the same shape, but not necessarily the same size; their angles are equal.
In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
A rectangle. If the sides are the same size, it's a square.
Rectangle or square. If all the sides are the same size then it is a square. if not, it is a rectangle.
An equilateral triangle, a square, a rectangle, an octagon.
Any parallelogram except a rectangle.
Same shape same angles but smaller size
They are all 90
Ninety degrees.
A rectangle may be called a parallelogram but they are both 4 sided quadrilaterals. A parallelogram can be called a rectangle if all four angles are right angles (90 degrees). A parallelogram can be called a rhombus if all four sides are the same size. A parallelogram can be called a square if all four angles are right angles and all four sides are the same size
When you enlarge or reduce a figure, the angles between the lines in the figure will remain the same. The ratio of the lengths of corresponding sides will also remain the same. Additionally, the shape of the figure will generally stay the same, although its size will change.
Similar polygons have congruent angles and the same shape (but not necessarily the same size). Since the shape of a square and a rectangle is different from the shape of a trapezoid, they are not similar to it.
A Rectangle is any four-sided shape where the angles inside all four corners are right angles (90 degrees). A square, therefore, is a rectangle where all the shapes are the same size. A parallelogram is any four sided shape where sides are the same length as the one opposite, but not at right angles to each other.
A rectangle is a shape which has all inner angles equal to 90 degrees. A square is A RECTANGLE that has all sides of the same size. Therefore, using informatical slang, SQUARE INHERITS RECTANGLE.
