Is a right angle triangle still an obtuse?
no it is its own type of triangle class
If a triangle has one acute angle is the triangle necessarily acute?
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
Is a right angle still a right angle if you turn it upside down?
Yes, the angle is still 90 degrees so it is still a right angle.
Can a triangle have an obtuse anlge and a right angle'?
No. ================================ Another contributor waxed more verbose: The three angles inside a triangle must add up to 180 degrees. A right angle has 90 degrees, and an obtuse angle is one with more than 90 degrees. You'd have more than 180 degrees right there with those two angles, and you'd still need another angle in your triangle. So it doesn't work
Where does Pythagoras's rule not work?
Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)
What is one geometry rule that the Greeks discovered do we still use today?
It is Pythagoras' theorem that is applicable to any right angle triangle.
Can one angle of a right triangle be 100 degfrees?
no, the definition of a right triangle is that one of its angles is 90 degrees while the other 2 are 45 degrees wrong... the other angles can be any angle less than 90 so long as one angle is exactly 90 degrees it is still a right triangle. ps. it is more appropriate when improving answer to add your comment not delete someone elses... your absolutely right. that was my bad. that was actually an awful answer on my part. didn't mean to delete yours.
Why is the greatest number or a right angles a triangle can have is one?
Draw a perpendicular line, then cross it with a horizontal line. Where the lines cross there are four right angles. Each angle measures 90 degrees and the total number of degrees is 360. By definition, any triangle will consist of a total of 180 degrees, no matter what the length of the legs. If the right angle consists of 90 degrees, then there cannot be another right angle in the triangle, because the 90 degrees still available must be split between the other two angles.
What is the sum of the measures of the three angles of a scalene triangle?
In a scalene triangle, the angle sum is still 180 degrees. What defines a scalene triangle is that it has three sides with different lengths, and therefore, also different angles. It can be a right triangle for example, with the angles 30, 90, and 60 degrees. It's angle sum always sums up to 180 as in all triangles. Note: It doesn't have to be a right triangle. It can be any kind of triangle as long as it has three different angles and sums up 180 degrees.
What are the properties of an acute triangle?
All the interior angles are less than 90 degrees ( or a right angle ) Sum of all the angles is still 180 degrees. kapm
Is a right vertical angle a vertical angle still?
No. Or at least, I think not.
Is a left angle obtuse?
nope, it's still a right angle
