the paper represented the analysis method of triangle grid phased array. Moreover, the infinite phased array with WAIM (added with metallic iris plate on each aperture of waveguide element and covered with dielectric sheet) in front of the array was analysised and its property of wide-angle mat...
Since the diagonal of a rectangle forms a right-angled triangle with its sides, the diagonal becomes the hypotenuse and its value can be calculated using the Pythagoras theorem. For example, if the length of a rectangle is given as 4 units and the width is 3 units, we can find the ...

(Solution by Flamedragon). Note that a triangle with side lengths 10, 10, 12 is essentially 2“6, 8, 10” right triangles stuck together. Hence, the height is 8, and our area is 48. So, the length of the rectangle is 484=12, and our perimeter P=2(4+12)=(D)32....
Because the diagonal forms a right triangle, you can use thePythagorean theoremto calculate the length of the diagonal. The Pythagorean theorem states: a2+b2=c2a^{2} + b^{2} = c^{2}a2+b2=c2 The formula to calculate the length of a diagonal that bisects a rectangle is: ...
