Can a triangle have 3 equal sides and one obtuse angle?
no
How many equal sides does an obtuse triangle have?
None normally but if it is in the shape of an isosceles triangle then it will have 2 equal sides.
What are all the three triangles called?
Equilateral: equal sides and angles(60 degrees) Isosceles: two equal sides and angles Scalene: no equal sides or angles right triangle: has a 90 degree angle in it obtuse triangle: has an obtuse angle in it acute triangle: is made up of all acute angles
Can an obtuse triangle have equal sides?
if you mean ALL sides equal then no, because for a triangle to have ALL equal sides all angles must be equal (60 degrees), and an obtuse triangle must have an angle with 91 or more degrees. but if you mean TWO sides equal then yes. for example, a triangle with angles 40, 40 & 100 degrees would have two equal sides.
What triangle has an obtuse angle and no congruent sides?
A scalene triangle can have an obtuse angle and two different acute angles.
