The phrase "angle of the triangle" is correct and usable in written English.
It can be used in mathematical contexts when discussing the properties or measurements of a triangle.
Example: "To find the area of the triangle, we need to know the lengths of the sides and the angle of the triangle."
Alternatives: "triangle's angle" or "angle within the triangle".
"It's the longest angle of the triangle".
We can observe how far the star appears to move against the background galaxies in that time and find the angle of the triangle from that.
Results show relationships between the habitual posture in the sagittal plane, the angle of the triangle between the cervical and upper thoracic kyphosis and the vertical line defined by spine points C7/Th1.
Draw two circles at the top angle of the triangle.
Position the paper with the right angle of the triangle pointing up, or away from you.
Turn the paper so the longest angle of the triangle faces away from you.
To secure symmetry in the writing of these laws, the angles of the triangle are lettered A, B, and C and the lengths of the sides opposite the angles are lettered a, b, and c, respectively.
Yet if they do not exist at all, neither will the house, or the saw-the former in the absence of stones, the latter in the absence of iron-just as in the other case the premisses will not be true, if the angles of the triangle are not equal to two right angles.
The solution is as follows: if all angles of the triangle are less than 2 π 3, then the Torricellian point is the interior point from which each side subtends an angle of 2 π 3.
where A, B, C are three inner angles of the triangle Δ A B C. According to conditions (H3.1 - H3.4 H3.1 - H3.4ithen (46) holds if and only if Δ A B C is a normal trianglequalityin, B ∗, C ∗ are the midpoints of line segment [ B C ], [ C A ], [ A B ], respectively.
According to Pythagoras' theorem and basic trigonometry, the relationship between the outer and inner angles of the triangle and lengths of the sides is fixed.
