How do you draw a right obtuse triangle?
Triangles are either accute, obtuse, or right. To draw an accute triangle start by drawing an accute angle (less than 90 degrees). Then extend the ends of the angle and connect them making sure that both new angles are also acute. To draw a right triange first draw a right angle. Then extend the angle and connect to form two accute angles. To draw an obtuse triangle first draw an obtuse angle (greater than 90 degrees). Then extend the sides of the angle and connect creating 2 accute angles.
Argument to showing that an equilateral triangle cannot have a right angle?
If you have an equilateral triangle ABC, then draw the line from A to D, the mid point of BC. Then in trangles ABD and ACD, AB = AC (equilateral), BD = DC (D is midpoint), and AD is common so these two triangles are congruent and so angle ABD = angle ACD. That is, angle ABC = angle ACB. Similarly the third angle can be shown to be the same. Thus an equilateral triangle is also equiangular. Now, sum of the interior angles of any triangle is 180 degrees. So since sum of three equal angles measures is 180 degrees, they must be 60 degrees each, i.e. NOT 90 degrees so there is no right angle..
How can you draw an angle over 180 degrees?
draw the outside angle if you want to show 270 degrees then you draw a 90 degree angle but draw the circle outside of it
How would you construct an isosceles triangle if only given the altitude to the base and a base angle?
Start with the altitude (height) and draw that. Draw the actual length of the altitude on your paper, or draw it to scale. Naturally you'll draw it down the middle of your paper parallel to the sides (perpendicular to the bottom) of your paper. Now that you have your altitude, draw a line perpendicular to it across the bottom. Your base will be on that, but we don't know how big it is yet. Let's work with your base angle, but indirectly. You have a vertical line perpendicular to another line. There are two right angles formed, one on each side of the vertical line. If you could draw in one side of your isosceles triangle, you'd have a right triangle that represents half your isosceles triangle. The altitude divides your isosceles triangle exactly in half down the middle. This right triangle will, like all triangles, have interior angles that add up (sum) to 180 degrees. Now we use the base angle. You have the 90 degree angle, and the base angle. That base angle and the "top" angle will add up to 90 degrees, and that's so that these two angles and the 90 angle where the altitude meets the base will add up to 180 degrees. That means the base angle and the top angle will have to add up to 90 degrees. Subtract your base angle from 90 degrees and you'll have your "top" angle. Get you protractor, place it at the top of your altitude, and mark the "top" angle. Now draw a line from the top of the altitude on this angle you set, and continue it to the base. That's one side of your triangle. Repeat this on the other side and your isosceles triangle will appear.
Is it possible to draw a triangle that has only one acute angle?
no
Can you draw a right angle equllarteall triangle?
No because each 3 angles of an equilateral triangle measures 60 degrees.
How do I draw a right angle?
A right angle measures 90 degrees
What angle do you draw for 18 degrees?
An acute triangle.
Is it possible to draw a unique triangle with angle measures of 35 degrees65 degreesand 100 degrees?
No because the 3 interior angles of any triangle add up to 180 degrees.
Show how to construct a 120 degree angle?
draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
Can you draw an equilateral acute triangle?
Yes because the measure of each angle in an equilateral triangle is 60 degrees which is an acute angle.
Can you draw an obtuse triangle?
Yes, its a triangle that has one obtuse angle (an angle over 90 degrees) and two acute angles (angles that are les that 90 degrees).
How many triangles exist with the given angle measures 55 degrees 45 degrees 90 degrees?
No triangle exists with the given angle measures. None because the given angles add up to 190 degrees and the 3 angles in any triangle add up to 180 degrees.
Can you draw a triangle with an obtuse angle?
No problem at all. Here's one: 150 degrees, 25 degrees, 5 degrees.
The ratio of the angle maeasures in a triangle is 5 4 1 draw and classify the triangle by its angle measurements?
It will be a right angled triangle with angles of 90, 72 and 18 degrees.
Can you draw an obtuse triangle with angles measuring 45 89 and 46 degrees?
Yes. Triangles can be classified by the measures of their angles asacute, right, or obtuse. An acute angle has a measure that is lessthan 90°. A right-angle measures exactly 90°. An obtuse angle hasa measure that is greater than 90°.
How do you draw a right obtuse triangle?
