Velocity triangles in fluid machinery are graphical representations used to analyze the flow of fluid through the machine. They show the relative velocities of the fluid at the inlet and outlet of the machine, as well as the absolute velocity of the fluid. These triangles are used to determine the performance of the machine, such as the efficiency and power output. By analyzing the velocity triangles, engineers can optimize the design and operation of fluid machinery to achieve the desired performance. **

Rice triangles, also known as onigiri, are a popular Japanese snack made of rice formed into a triangular or cylindrical shape and often wrapped in seaweed. They are typically filled with ingredients such as pickled plum, salmon, or tuna. Rice triangles are a convenient and portable snack commonly found in Japanese convenience stores and are enjoyed for their delicious flavor and satisfying texture. **

Similar triangles are triangles that have the same shape but are not necessarily the same size. This means that their corresponding angles are equal and their corresponding sides are in proportion to each other. When two triangles are similar, their sides are in the same ratio, known as the scale factor. This property allows us to use the concept of similarity to solve various geometric problems involving triangles. **

Yes, both triangles are constructible. A triangle is constructible if its three sides can be constructed using a straightedge and compass. In the case of the first triangle, we can construct the sides of length 3, 4, and 5 using the Pythagorean theorem. For the second triangle, we can construct the sides of length 5, 7, and 8 using the Pythagorean theorem as well. Therefore, both triangles are constructible. **

Slope triangles are a visual representation of the slope of a line on a graph. They are formed by drawing a right-angled triangle on the graph, with one side parallel to the x-axis and the other parallel to the y-axis. The slope of the line is then calculated by comparing the vertical and horizontal lengths of the triangle. Slope triangles are a helpful tool for understanding and visualizing the concept of slope in mathematics. **

Isosceles triangles are a type of triangle that has two sides of equal length. This means that two of the three angles in the triangle are also equal in measure. The third side, called the base, is typically of a different length than the other two sides. Isosceles triangles have a line of symmetry that divides the triangle into two equal halves. **

No, not all axisymmetric triangles are isosceles. An axisymmetric triangle is a triangle that can be rotated 180 degrees and still look the same. Isosceles triangles are a specific type of triangle where two sides are equal in length. While an isosceles triangle can be axisymmetric, not all axisymmetric triangles are isosceles. **
