Are some isosceles triangles acute?
Yes. Consider a triangle ABC with the following angles:A = 40B = 70C = 70Angles B and C are equal, which means the triangle is isosceles. All three angles are less than 90 degrees, which means the triangle is acute. Therefore, the triangle is both isosceles and acute.
What are some ways to estimate the measure of an angle?
You can estimate angles by using right, acute, and obtuse, or just by simply using a protractor. A protractor isn't a person who is a pro at driving tractors, its a semi-circle shaped math tool. XD
How do you find the perimeter of a triangle with perpendicular height?
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
How do you find the measure of an angle to the nearest degree?
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
What letters of the alphabet have a right angle and an acute angle?
If you are asking what letters have BOTH types of angles in the same letter, the answer is: only KThese letters have acute angles:Upper case letters: A K M N V W X Y ZLower case letters: k v w x y zThese letters have right angles:E F H I K L T and f t
Is it possible for some triangles to have none exterior angle obtuse angle?
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.
Does a triangle have 2 obtuse angles?
Some have one obtuse interior angle, others have none. A triangle can have no more than one obtuse angle.
Is it true that an obtuse triangle can have a right angle?
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
Does every triangle have to have an obtuse angle?
no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.
Do some triangles have one obtuse angle and two acute angles?
Yes. For example, an isosceles triangle with one angle of 120 degrees, and two of 30 degrees.
What are some different triangles?
You have acute, right, and obtuse triangles when referring to the measure of the largest angle, and you have equilateral, isosceles, and scalene triangles when referring to the congruency of the triangle's sides.
Which shapes do not contain obtuse angle?
Some examples are: circle, square, rectangle, right angle triangle, equilateral triangle
How do you spell the kinds of triangles?
Some types of triangles are: scalene triangle equilateral triangle isosceles triangle acute triangle right triangle obtuse triangle
How many angles does an obtuse angle have?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. In addition there are concave octahedra. Some of these will have no obtuse angles, others will have several.
Some triangles have two obtuse angles and one acute angle?
Spherical triangles as on the earth's surface.
Can you show a picture that has a triangle with 2 acute angles?
Go to google.com/images and search "obtuse isosceles triangle", that should get you some good examples.
What are some characteristics of acute triangle?
it s a angle that is less than 90 degrees.
