True or false:
A deltoid is composed of an isosceles triangle and a right triangle.
True or false:
A deltoid is composed of an isosceles triangle and a right triangle.
True or false?
In a concave deltoid, the sum of the angles is 180.
Determine whether the following is true or false:
A deltoid has two pairs of adjacent equal sides.
True or false?
A square is a deltoid.
True or false?
A rhombus is a deltoid.
True or false:
A deltoid is composed of an isosceles triangle and a right triangle.
In order to answer the question we must recall some properties of the deltoid. For this purpose, let's draw the deltoid where we connect every two non-adjacent vertices (meaning - draw the diagonals) and mark the intersection of the diagonals with the letter :
Let's recall two properties of the deltoid that will help us answer the question ( from the previous drawing):
a. Definition of a deltoid - A deltoid is a convex quadrilateral with two pairs of adjacent equal sides:
b. The diagonals in a deltoid are perpendicular to each other:
Now we can clearly answer the question that was asked, and the answer is that the deltoid can indeed be described as composed of two isosceles triangles since triangles: are isosceles - (from property a' mentioned earlier):
Or can be described as composed of four right triangles, since triangles: are right triangles (from property b' mentioned earlier):
Therefore, the correct answer is answer a'.
