∵PA=PB,∴AD=BD，
In Rt△ACB, AC=4, BC=2,
∴AB=AC2+BC2=25,∴AD=5，
∵tan∠cab=pdad=bcac,∴pd=52> 1，
∴⊙P is separated from straight line AB; ?
(2) As shown in Figure 2, when ⊙P is tangent to point M and connected to PM with straight line AB,
Then PM⊥AB,
∠∠CAB =∠CAB，∠AMP=∠C=90，
∴△APM∽△ABC，
∴APAB=PMBC，
AB = 25，
∴4? PC25= 12，

As shown in the figure, in AABC, ZB = 90°, AB=5cm, BC=7cm, and point P starts from point A and goes along ray AB to point 20 17-09. AC=8, point D is the midpoint of BC, the intersection AC of DE⊥BC is at point E, point P is the fixed point of ray AB, and point Q is 202011-kloc-0/6. In the known Rt△ABC, ∠ A = 30. The intersecting ray AC is at e point 3720 16- 12-02. As shown in the figure, straight line AB and CD intersect at point O, ∠ AOC = 30, and the center of circle P with radius of 1cm is on ray OA. PO = 6 cm at first. As shown in the figure, the circle P is1309 2013-13, and it is known that ∞△ABC = 90°, and point P is any point on the ray BC (point P does not coincide with point B), with AB and AP as sides respectively. BC=2, point P is a moving point on ray CA, with P as the center and 1 as the radius, make a circle P302010-131as shown in the figure, at Rt△ABC, ∠ A = 90. AC = the crossing point p is 422016-1-23 (as shown in the figure, in △ACB, ∠ ACB = 90, AC = 4°, BC = 2°, and point p is the moving point on ray CA.
