Using indirect reasoning to show that a triangle cannot have two right angles?
Triangles total 180 degrees. Triangles have three angles. Two angles of 90 degrees total 180 degrees.
How do you prove a right angle using coordinate geometry?
Right angles are created by perpendicular lines. You first have to find the slopes of the lines. You know lines are perpendicular when the slopes are negative reciprocals. For example: If you find the slope of Line AB to be -2, in order for the lines to form right angles, the following line would have to be 1/2. So getting back to your question, calculate the slopes and show they are negative reciprocals. Hope I Helped!
Can you show me things that are shaped like a trapezoid?
a dustbin like= ______________ \ / \ / \ / \ / '''''''''''''
Can you show me a quadrilateral with one right angle one obtuse angle one acute angle and two parallel lines?
Think of your regular trapezoid (half a hexagon). Now cut it in half with a line perpendicular to the top and bottom. You can see the right angles along one side. The top and bottom lines are parallel. The seond angle on the bottom is acute, and the second top is obtuse. Can't be bothered to provide diagrams, though. Draw them yourself.
Can you show me a right trapezoid?
____________ / | /_____________ | Crappy drawing, I know, but a right trapezoid has two right angles(right side of picture), and two supplimentary non-right angles(left side of drawing). This is still a trapezoid because in order to be a trapezoid, there must be one and only one pair of parallel lines, and four sides. That's it, thus this is a possible trapezoid.
How do you prove that a quadrilateral is a right trapezoid?
To prove that a quadrilateral is a right trapezoid, you need to show that it has one pair of parallel sides and one pair of right angles. This can be done by using the properties of parallel lines and perpendicular lines.
What are 3 ways to show a trapezoid is a rhombus?
It's sides angles and shape or form
Can you show me what perpendicular is?
Perpendicular means "at right angles to". L is an example of two lines that are perpendicular to one another.
How do you prove a trapezoid is isoceles?
To prove a trapezoid is isosceles, you need to show that the legs (the non-parallel sides) are congruent. This can be done by demonstrating that the base angles opposite these sides are congruent. You can use the triangle congruence postulates or the properties of parallel lines and transversals to establish the equality of these angles.
Can you show me a example of a perpendicular question?
When straight lines are perpendicular to each other they create right angles of 90 degrees

Can you show me a drawing of a pentagon with no right angles?
A regular pentagon doesn't have any right angles ! See related link.
Show an example of a triangle with an obtuse angle and a right angle?
This is not possible. If a triangle is a Right angled triangle then the sum of the two angles which are not right will be = 90 [Angle Sum Property] That's why you see.
How can I show that the angles are congruent without measuring the angles?
You would have to be given other information about the angles that would let you deduce that they are equal. For example any two right angles are equal. If two parallel lines are cut by a transversal, the alternate interior angles are equal.
How can you show a pentagon with no right angle?
If you wan't to show that a pentagon has no right angles, then don't put any right angle signs in the figure.
Can you show me a quadrilateral with 2 right angles?
a square, rectangle, rhombus.....
