Let's say the intersection of the two subspace U∩VU∩V. Assume existing an element w∈U∩V,w≠0w∈U∩V,w≠0 then there exist an example violating the orthogonality condition. w∈U,w∈V,wTw=∥w∥2≠0w∈U,w∈V,wTw=‖w‖2≠0 Then this contradiction tells you ...
Give reasons. (i)If two lines are intersected by a transversal, then corresponding angles are equal. (ii)If two parallel lines are intersected by a transversal, then alternate interior angles are equal. (iii)Two lines perpendicular to the same line are perpendicular to each other. (iv)Two...
If two triangles are similar, then the ratio of side lengths will be constant. It need not be 1 and hence, the side lengths need not be the same. The... Learn more about this topic: Similarity in Geometric Shapes from Chapter 42/ Lesson 3...
Can lines and planes intersect with each other? Explain. Determine whether the two lines L_1 : x=t, y = 1-t, z=2+3t\L_2 : x = 2+2s, y = 2s, z = 3+s are parallel, skew or intersecting. Given the descriptions of two lines, find...
In the following statements, ( ) is a true statement.(A) If a b ac , then b c.(B) A right-angled triangle must not be an isosceles triangle.(C) On the same plane, two lines perpendicular to the same line are parallel.(D) Two corresponding angles are always equal. 相关知...
If they are equal, then the lines are perpendicular. If the they are not equal, then the lines are not perpendicular.( m_1=4,m_2=-(0.1‾6))The equations are not perpendicular because the slopes of the two lines are not negative reciprocals.Not Perpendicular...
