The phrase "acute triangle" is correct and usable in written English.
It can be used in mathematical contexts to describe a triangle where all three angles are less than 90 degrees.
Example: "In geometry class, we learned that an acute triangle has angles that are all less than 90 degrees."
Alternatives: "sharp-angled triangle" or "narrow triangle".
The original shape of the Hall sides represents an isosceles acute triangle on whose vertex the Hall contact is formed.
It is well known that Δ A B C is an acute triangle if and only if [ A A ∗ ] ⊥ [ B C ], [ B B ∗ ] ⊥ [ C A ], [ C C ∗ ] ⊥ [ A B ]. implies that | Δ A ∗ B ∗ C ∗ | takes the minimum.
This is illustrated as an acute triangle beside the two cameras in Figures 1 and 3, and its geometry is determined by the length of the camera unit and the parameters of image combination.
Case 3(a): If the real part of ({mathbf {h}}_{12}^{H}{mathbf {h}}_{22}) is positive, i.e., (mathfrak {R}left ({mathbf {h}}_{12}^{H}{mathbf {h}}_{22}right)>0), the solution of v 2 is in the direction of the altitude of the acute triangle as shown in Fig. 3(a).
A fast marching method is adopted to acute triangle meshes in [27].
An acute triangle must have 3 acute angles.
This work is focused on the design of efficient multigrid methods for discretizations on Voronoi meshes associated with regular refinements of acute triangles.
The dart may be bisected along its axis of symmetry to form a pair of obtuse Robinson triangles (with angles of 36, 36 and 108 degrees), which are smaller than the acute triangles.
The T rhomb may be bisected along its long diagonal to form a pair of obtuse Robinson triangles; in contrast to the P2 tiling, these are larger than the acute triangles.
Then, divide the perimeter into smaller rectangles and triangles - for instance, a bay window might look like a rectangle with two acute triangles on each side.
[Use acute triangles with the sharpest angle merging with the corner of the trapezoid.Keep your triangles small (1/4-1/5 the side of the face) or your tiger look like a puppy.] Draw a triangle in the center of your trapezoid; this is the tiger's nose.
