How many lines of symmetry does an obtuse angle isosceles triangle have?
Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
Facts about intersecting lines?
yes they intersect, they can also intersect at different angles, obtuse, right, and obtuse
What is an equilateral rectangle?
It's a square. A rectangle is any polygon with two pairs pf parallel sides all intersecting at perpendicular angles. It's diagonals are also congruent. This is also true with a square. So, a square could also be considered a rectangle. The only difference is that a square's sides all have to be the same length, and a rectangle's doesn't. 'Equilateral' means all the sides are equal. Therefore, an equilateral rectangle is a square.
An equilateral triangle can also be called?
a tetraheddron.
What is the name of a triangle where all sides are of equal lenght?
An equilateral triangle. Since the angles are automatically congruent, it could also be called regular.
Can an equilateral triangle also be obtuse?
No if one angle is obtuse then they can't all be obtuse
What does an obtuse equilateral look like?
There cannot be an obtuse equilateral triangle. A rhombus is an equilateral quadrilateral with two obtuse angles (and two acute ones). Not sure if that counts as an obtuse equilateral. All regular polygons with more than four sides will be obtuse and equilateral. There are also other polygons that will meet these requirements. These will be squashed polygons in the same way that a rhombus is a squashed square.
Can an equilateral triangle also be abtuse triangle?
No, a triangle can only be equilateral if all of its angles = 60 degrees and 60 degrees is acute, not obtuse.
What is three types of triangles?
They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles
What are three ways in naming a triangle?
Right angle, equilateral, isosceles and there are also scalene and obtuse triangles.
Is a obtuse a scalene in a triangle?
The definition of an obtuse triangle is a triangle with an angle exceeding 90o. A scalene triangle is a triangle in which no two sides are of equal length. Therefore, it is possible that an obtuse triangle is a scalene triangle. However, it is also possible for an obtuse triangle to be an isosceles, in which two sides are of equal length. On a final note, it is impossible for an obtuse triangle to be an equilateral; equilateral triangles always have angles of 60o.
Can you name all of of the triangles for math?
equilateral triangle, scalene triangle, and isoceles triangle Also, acute, obtuse, and right
How many lines of symmetry does an obtuse angle isosceles triangle have?
Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
Does a scalene triangle have 2 obtuse angles also?
It's impossible for a triangle to have 2 obtuse angles. A scalene triangle in one that has no equal angles or sides. It could have 1 obtuse angle or it could have 0.
Why is a hexagon not equilateral but equiangular when it is formed with lines connecting the corners of squares that are on each side of an equilateral triangle?
Equilateral triangles have three 60' angles, and the angles of any triangle always add to 180'. Attaching squares to each side of an equilateral triangle would also form three obtuse angles (360' - 90'- 90' - 60' = 120') and the resultant obtuse Isosceles triangles' hypotenuses would be greater in length than any side of the square since its two equal sides are the same length as the square. However, the angles of any corner of the newly formed hexagon would be 90' from the square plus 30' (30' = (180' - 120')/2) from the obtuse triangle, making this hexagon equiangular, but not equilateral.

Which triangles have one obtuse angle?
If the triangle has an obtuse angle then the other two angles must sum to less than 900. The triangle therefore CANNOT be an equilateral triangle. It CAN be an isosceles triangle with the two equal angles summing to less then 900. For Example, 1200, 300, 300. It could also be a scalene triangle with angles such as 1200, 500, 100.
Can an equilateral triangle be either acute or obtuse?
No. An equilateral triangle must also be equi-angular, meaning that the angles can only ever have 60 degrees.
